Changes:
- improved: levels from 13 to 15 (maximum compression ratio)
- added: a new parser: LZ5HC_optimal_price_bt

Please help me with fuzzing. Here is a quick comparison:

Code:
Compressor name              Compression Decompress. Compr. size  Ratio

Slowness makes the higher levels pretty much unsuitable for fuzzing, but I do some basic tests.
