// Compiler optimizer (at least I think so :)) generated following tables to speedup volume calculation for left & right volume.
I'll remove these tables in future and add normal mathematical interpretation of volume calculation.
Add formula for generating the volume table. (linear curve)

If there is no A3 opcode in sequence (as in SENSUI.SND for example), default value 0x7f is used.
