py-magic-wormhole: Add version 0.12.0

This package provides a library and a command-line tool named
wormhole, which makes it possible to get arbitrary-sized files and
directories (or short pieces of text) from one computer to
another. The two endpoints are identified by using identical "wormhole
codes": in general, the sending machine generates and displays the
code, which must then be typed into the receiving machine.

The codes are short and human-pronounceable, using a
phonetically-distinct wordlist. The receiving side offers
tab-completion on the codewords, so usually only a few characters must
be typed. Wormhole codes are single-use and do not need to be
memorized.
