This adds dumping for the tune= field that was just added in commit
276118107, but also:
* Instrument name gets put in a comment at the end of line - like the
current configuration in config.py.
* Instrument calls get split across two lines when there are many
parameters, to try to keep to 80 columns.
* off1= and off2= parameters now get outputted as +x or -x rather than
just x or -x.
Python 2 is very near end-of-life, and Python3-compatible changes to a
few scripts introduced compatibility problems with 2.7 again. It went
unnoticed for me since my system symlinks "python" to "python3", but
it broke the build on systems where that symlink is still python2. At
this point in time, I feel it is worth targetting modern Python and
forgetting about 2.7.
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.
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...).
Tweak the code used to build the GENMIDI Lump so that it properly
supports Python 3 for build. Tested use cases were:
* Normal build
* a2i-to-sbi script to convert AdTrack2 instruments to SBI format
* dumpgenmidi script to dump the instruments from a GENMIDI lump.
* Running genmidi.py, sbi_file.py, a2i_file.py standalone to print the
contents of files in their respective formats.
