* Fix analogWrite channel available verification

The last channel allocated is number 0, which conflicted with the value given to an uninitialized pin, giving the "No more analogWrite channels available!" error when trying to use it
Pins are now given the value -1 to indicate that they are not used so channel 0 can be used without errors.

* Fix incorrect array initialization

Keeping array of zeros for `pin_to_channel` and shifting stored channel
values by +1 to keep the pin with channel 0 from being interpreted as unused.

* added lilygo t-display (esp32) board

this board is the predecessor to the already included lilygo-t-display-s3

added USB defines for t-display

* implementation of @P-R-O-C-H-Y comments

* added build properties to fix failed compilation

SD lib - AcquireSPI on ff_sd_status

Reimplemented flush in WiFiClient

Allows changing HW CDC Buffer Size after or before begin()

Fixes ESP32 BT Memory Releasing

Removed duplicate MDNS.begin() call in example

Added special handling of the `ARDUINO_BUILD_CORE` macro required only for the core files

* Added the ReadTheDocs configuration file

* File renamed to YAML

In WiFiSTA you can ask for the subnet mask, but not in WiFiAP.
Only the CIDR is reported.
Therefor the missing method is added to have the same features in softAP as well.

The constants that need to be passed to gpio_matrix_in and gpio_matrix_out
to detach an input or output pin from a peripheral vary by platform.  Use
SIG_GPIO_OUT_IDX to detach an output, and GPIO_MATRIX_CONST_ONE_INPUT
and GPIO_MATRIX_CONST_ZERO_INPUT to detach an input.  ESP32 before IDF 4.0
didn't define GPIO_MATRIX_CONST_*_INPUT, so add compatibility #defines
for GPIO_FUNC_IN_LOW/HIGH.  GPIO_FUNC_IN_LOW/HIGH exist in IDF 4.0+, but
can't be used because they have the wrong values for ESP32-C3 at least
in IDF 4.4.3 (https://github.com/espressif/esp-idf/issues/11737).
