Add a symlink to the repo to point to the ArduinoAPI submodule instead
of requiring manual addition after athe first `git clone`.

Added size validation to the EEPROM begin, but forgot to set the class
variable with the new adjusted size.
Fixes #10

Forgot to `git add` a wiring file.  Fixes #11

Use CDC class for the USB serial port

Fixes #8 and some other weirdness seen when going between computers.
Use the CDC and not MISC class to identify the Pico

Allow for spaces in paths of the platform/core/etc.

Properly quote all instances of file paths and runtime paths in the
platform file to ensure thathaving a username with spaces in it won't
break the compile.

Fixes #6

Allow ::print() to go to a serial port instead of dropping.
Will allow for full VFS/etc. with standard FILE semantics, or at least
::putc and ::getc on STDOUT/STDERR to work.

Allows Adafruit GFX libraries to be used

pico-sdk-lib/build.sh will compile a libpico.a file from scratch using
the selected pico SDK directory.

Avoid any short pulses which could cause servo twitches or damage by
adding a shutdown command to the PIO program and checking it's in that
safe part of the loop before detaching the servo.

Arduino API doesn't support printf on Print objects, so bring our own.

/system is only downloaded tools
/tools is all scripts/submodules that are part of the main core
