Description of Change

This PR adds support for Espoir, a mikroBUS PoE+ devboard, by Connaxio inc. However, the ESP32-MINI-1 is a single core CPU, so Connaxio will provide the builds for its devboard until single core CPUs are officially supported. Adding these modifications to the official repository will limit discrepancies between Connaxio's fork and the main repo.

Tests scenarios

Tests include Ethernet, SPI, USB, I2C, UART (1-wire).

More info: https://www.connaxio.com/electronics/espoir/

espressif/esp-idf / components/driver/include/driver/uart.h defines the API:
esp_err_t uart_set_pin(uart_port_t uart_num, int tx_io_num, int rx_io_num, int **rts_io_num**, int **cts_io_num**);
uartSetPins uses that api but alls it with swapped CTS/RTS pins as its API uses a different pin ordering: 
uart_set_pin(uart->num, txPin, rxPin, **ctsPin**, **rtsPin**); 

This fixes the wrong order in the function uartSetPins

When building the core with `-Wextra` a few locations have `case:`
fall throughs or skipped field initializers.

Add proper comments for B64 cases to avoid GCC warnings

Initialized unused fields in Tone and WiFiGeneric to avoid missing
field initializer warnings.

add a comment to make it clear, since platformIO still creating the `spiffs.bin` for filesystem image. The file name `spiffs.bin` is so much CONFUSING! it makes the user fill the LittleFS creating is fail.

The asterisk needs to be quoted.

* Fix timerAttachInterrupt() and timerDetachInterrupt() for migration to IDF 4.4

* Fixing log messages as per request

Better allocate the buffer for f_mkfs from the heap otherwise the stack requirement of this library is huge due to a work buffer allocated for f_mkfs in sdcard_mount. The work buffer is only needed if argument format_if_empty is set true (which is by default false). 
This change is quite important if you plan to use this library in a task. as now it increased the tasks stacks size by 4k, even this memory is never used if users are not aware of the large stack requirement during init this library may have other variables on stack that would have written memory outsides its range which can cause various side effects.

The internal _isRemoteAddressSet variable is set to true
when calling connect() functions. If connecting fails _isRemoteAddressSet
needs to be re-set to false, otherwise other functions, such as
discover() will fail without clear error messages.

... as availability depends on compilation parameters.

Fixed channel / unit selection for ESP32C3 (has only 5 channels on 1 adc unit).

Removed unnecessary includes.

Fixed different attenuation on channels to be taken in care in __analogReadMilliVolt.

All chips in __analogReadMilliVolts now use adc characteristics + calculation from raw to voltage as ESP32 does.

Fixes inability to flash the bootloader with esptool 4.x on device with flash size different than the default

Summary

Added compiler.warning_flags to all chips in platform.txt to reflect users setting of warning level output during compilation (set up in Arduino IDE preferences)

Impact

When a warning is set to none the compilation will no longer display warnings

* Changed in pinMode() default  intr_type

pins default configuration has intr_type =  GPIO_INTR_DISABLE
With this implementation, it will set the intr_type to previously set intr_type. It will no longer disable interrupt, when pinmode is called multiple times on same pin with interrupt enabled.

Workflow is scheduled.

It looks like the depedency on the Test job was not enough and the Event
job was triggering even without the label.

upload-idf-component.yml action was only running for tags like v*, while in this project tags like 2.0.3 are used. With this change, the workflow will run for all tags.

Implemented a new method for allowing folks to preserve their TinyUF2 bootloader setup when flashing their boards via Arduino IDE, without being locked out of not using it if they want to use a different partition.

Adafruit had already added support for keeping (reflashing) the TinyUF2 bootloader when flashing via Arduino IDE (thanks @ladyada ), but the issue with it is it doesn't allow users to not choose to use it. Even if they select a specific partition scheme from the partition drop down list, it ignores that selection and only does the TinyUF2 partitioning/bootloader thing.

We wanted to let users choose between keeping their TinyUF2 partitioning and bootloader, or choose another partition scheme and have the TinyUF2 support disabled and just operate like they would expect.

We've implemented this by adding the TinyUF2 support as a partition scheme option, and using these build options in platform.txt to choose to use teh UF2 path or use the standard path.

This fixes possible issues when developers specify arbitrary partition files
using relative or absolute paths.

Additionally, hyphens in filenames are replaced with underscores to
avoid compilation warnings "ISO C++11 requires whitespace after the macro name"
