New faster and shorter decompressors

This update is mostly about better integration of improvements by uniabis, with spke contributing several smaller size optimizations.

Time-efficient LZSA2 decompressor
...
This commit provides a time-effecient LZSA2 decompressor for
the 8088 (and higher) CPU. Decompression speed is roughly 50% faster
than ZX7 on the same hardware.

Submit 8086-optimized decompressor using jump tables
...
Because the 8086's BIU is more efficient and can read a word in
a single operation, we can skew LZSA1 decompression faster on 8086
by using a jump table to eliminate 2 comparions.
