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 Scott Shawcroft's copyright as per
   the LICENSE file.
 * The favicon.ico file has been tagged with CC-BY-4.0 license as per
   adafruit/circuitpython#2887 (comment)
   and Phillip Torrone's for Adafruit Industries copyright.
 * All configuration files have been tagged with Scott Shawcroft'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).
 * In the templated library structure, I've added a double copyright line
   for Scott Shawcroft _and_ the authoring person/company as per previous
   template in at least some of the files. Please let me know which others
   need to be tagged. There is some space for the _template_ having MIT
   license while the _generated_ file having Unlicense, or them having
   different copyright altogether.
 * Since all three of the licenses are used in both the repository itself
   and the generated repository in the cookiecutter, they are currently
   duplicated.
