Add non-standard library calls used by String

Borrowed from https://github.com/esp8266/Arduino , include dtostrf() and
others.

Fixes #13

Thanks to @me-no-dev, the serial monitor issue was traced down to
DTR/RTS settings in boards.txt.  Clean those up and the monitor seems to
work perfectly now.

Use chunks not bytes to transfer data to host, like in the serial_usb
SDK.

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.
