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.
