Apply SPDX copyright and license headers in compliance with REUSE.

The REUSE specifications[1] are meant to make it explicit and easier to
apply code licensing information for a project. The provided lint tool
makes it easy to ensure all the content (code and not code) is tagged.

Important notes:

 * All the code (and documentation) that otherwise didn't have an explicit
   license headers have been tagged with ladyada's copyright as per the
   LICENSE file.
 * favicon.ico and CODE_OF_CONDUCT.md have been synced from the
   source-of-truth repositories.
 * All configuration files have been tagged with ladyada's copyright and
   Unlicense[2]. The current REUSE recommendation is to use CC0-1.0, but
   that has… side effects. There's some discussion in [3] about the
   recommendation for likely-uncopyrightable files (such as configuration
   files).

 # Using ESP32 co-processor GPIO pins with CircuitPython ESP32SPI
 
 As of NINA firmware version 1.3.1, the ESP32SPI library can be used to write digital values to many of the ESP32 GPIO pins using CircuitPython. It can also write "analog" signals using a float between 0 and 1 as the duty cycle (which is converted to an 8-bit integer for use by the NINA firmware). Keep in mind that these are 1000Hz PWM signals using the ESP32 LED Control peripheral, not true analog signals using an on-chip DAC. More information can be found here:
