v2.0.0

New commits

• Reduce allocations & accept bytes and bytearray inputs (#22) a7c41df
• Support PyPy builds - not Windows (#28) e94b30f
• Support de/compress_into (#26) 67f368c

Notes

• Variants are moved to their own modules. ie snappy_compress is now cramjam.snappy.compress
• Accept both bytes and bytearray objects and returns the same.
• Accept an optional output_len when the output of (de)compression is known; giving a 1-3x performance increase
  • While this is supported in snappy as well, when using bytearray as input, the output size is automatically calculated and the resulting buffer is resized after (de)compression.
• New de/compress_into for all variants, except lz4
• PyPy3.6 supported for OSX and Linux
• Python 3.9 support
