/* 2019, g Heavy Industries
Blessed mother of Christ, please keep this readable
and protect us from segfaults. For thine is the clock,
the slave and the master. Until we return from main.
Amen.
This is a stripped down version of the Georgi engine meant for use with
. As such serial-Steno features are disabled, chords are 16bits and
crap is removed where possible
