Fixes #28

Update pico-sdk to 1.1.2

Add methods to block the opposite core while doing flash updates.
Ensure opposite core is stopped in LittleFS and EEPROM while doing
flash updates.

Update documentation with new calls.

Fixes #120

* add keywords file

* Add PWM function definitions

Support running code on the second core by adding a setup1() and/or
a loop1() routine to a sketch.  These functions operate exactly like
the normal Arduino ones, and anything they call will be run on
the second core automatically.

Add a simple multicore example.

Using the official Raspberry Pi Pico datasheet and the Adafruit Feather
RP2040 schematic, set the default pins for peripherals to match.

Fixes #92

Keep a per-core IRQ stack for noInterrupts since each core has its own
enable/disable.

Make analogRead/analogWrite multicore safe

Add a mutex around the Tone mapping for multicore safety.

Fix #104

Fixes #96

Fix #100

Can't have cores/rp2040/api in the include path because the Arduino API
dir has a "String.h" file.  On Windows, because it is case-insensitive
normally, this overrides the POSIX "string.h" header leading to bad
stuff.

Add manual redirect includes for commonly accessed headers in the
cores/rp2040 path instead.

Missing Size field was causing the Arduino 2.0 beta to reject the JSON.

Fixes #93

Thanks to @me-no-dev for pointing out that the Picoprobe does UART
passthrough!

Update the ArduinoAPI with new macros/inlines that allow accessing
values that are not naturally aligned (i.e. an int at address 0x0001).

Fixes #79

Last step before 1.0. Docs for readthedocs.io.

Update the I2S API to mimic others where `setXXX` is called before
`begin()` to set the GPIO pins used.

The SDK would assert if a flash write/erase happened past the end of the
flash space it was built with.  So, 8MB chips would crash when accessing
offset 3MB, for example.

Avoid this by specifying the maximum flash available so the SDK won't
trip.

Fixes #76

Pull in the ESP8266 File/Dir/etc. filesystem and port LittleFS
and SD/SDFS to the RP2040.

See https://arduino-esp8266.readthedocs.io/en/latest/filesystem.html
for more information

Using the PIO-driven I2S from pico-extras, add I2S output support.

Be sure to `git submodule update --init` to get the new directories.

Heise.de seems to have been confused by the menu options for the
filesystem/sketch selection.  Explicitly list the Sketch and FS sizes in
each menu tem to avoid future confusion.

Instead of duplicating output call in all children, fork ArduinoApi and
add it in the Print base class.

Testing in #42.  Thanks @blurfl!

Build all 4 different boot_stage2 objects with SPI/2 and SPI/4 options.
Add a menu to the generic board to allow selecting between them.
Use the potato/4 boot2 for the Adafruit Feather until we have a better
version verified.
