v0.8.1
Changed : --ultra now enables levels beyond 19
Changed : -i# now selects benchmark time in second
Fixed : ZSTD_compress* can now compress > 4 GB in a single pass, reported by Nick Terrell
Fixed : speed regression on specific patterns (#272)
v0.8.0
Improved : better speed on clang and gcc -O2, thanks to Eric Biggers
