Using the black code reformatter, pass it over all our Python files.
This allows for a consistent style across the code base.
Exception: lumps/dmxgus/stats.py, for readability.
Split the piano and bass guitar groups into separate groups to give more
variation. Move several instruments around which don't fit, and move
several random percussion instruments into an enlargened "blank" group
since these percussion effects are not really similar to each other and
it's better to leave them out than play something that sounds wrong.
The tags are shorthand for the license of each file and avoid
copying the full license text into each one (and avoids having
to manually update the dates in each one...).
The main instrument groupings were already pretty good but there
was some room for improvement. The generated configuration sounds
pretty good now, even when using the 256KB config.
Regroup GUS percussion instruments based on personally having listened
to the samples in the GUS instrument set and identifying similar-
sounding instruments.
The indices of the percussion instruments were all off-by-one. These
should be 128+genmidi number, but were 127+ by mistake. This
considerably improves the percussion in Freedoom when using GUS.
Replace the current poor-quality handcrafted GUS configuration with
a script that programatically generates an optimized configuration
file based on statistical analysis of music from various popular WAD
files.
