With using of VGM specification, implement the import of YM2612 instruments from the VGM files
http://vgmrips.net/wiki/VGM_Specification

Algorithm is simple:

make the memory block that replicates YM2612's memory
every command write any register data into it (if DAC flag is toggled on, drop any commands related to channel 6, or export catched sample sequences as WAV files)
every non-zero delay fetch the data of registers, compare with existing instruments and append if case was not passed

Import from VGM files has been implemented:

Caching avoids duplicated instruments in total, list of imported instruments will contain unique entries
All volumes are forcedly aligning to the maximal possible level (carriers only in dependence from algorithm). This avoids duplicated entries are different by volume factor
