added negative compression levels

negative compression level trade compression ratio for more compression speed.
They turn off huffman compression of literals,
and use row 0 as baseline with a stepSize = -cLevel.

added associated test in fuzzer

also added : new advanced parameter ZSTD_p_literalCompression
