Fixed sf2mdta, inproved sf2mdt [Barry Harris]
- removed hack for row scroll table address in sf2mdt (bootleg layer render code doesn't use table, and the game isn't writing the address anywhere, hence the presence of the hack)
- aligned scroll 2 layer in sf2mdt
- boosted interleave when writing sound command to fix the issue of voice's being dropped
- decoded graphics in sf2mdta correctly
- hooked up sf2mdta reads and writes the same as sf2mdt with different a layer write layout
- hooked up sf2mdta work ram
