fc7b94876d Fix Y8950 ADPCM samples. 
Reverting back to before 70ead337f3, and setting register 8 to 256Kbit RAM mode.
This is what MSX has natively, and allows for the most compact sample storage with
only 4 byte alignment.

Additionally, setting register 8 before writing the start / stop addresses.

Back story:

VGMPlay MSX only supports Y8950 256K DRAM mode and ROM mode (for the latter
it makes sure address writes are shifted). 64K DRAM mode is not supported because
it’s not used by anything and the addresses are specified weirdly with some middle
bits having to be masked out.

The original code in Furnace before the change 70ead337f3 was almost correct except
it needed to set register 8 to 0 to select the 256K DRAM mode. It was set to ROM mode
so the address shift did not match up.

After 70ead337f3 (address shift change) it was also more or less correct except in
“furnacePCM” direct-sample mode the shift was not updated accordingly.

In 1a446c1cdd it selected 64K RAM mode, but for this the addresses need to be specified
differently (see Y8950 manual page 18), and it’s not really the best choice anyway.
