Bug fixes + local library

[cccs-rs]

Imported a copy of the pyswf library rather than changing the copy in my repo. Easier for someone else to make changes in the future.

Fixes:

• 'float' object cannot be interpreted as an integer
• TypeError: write() argument must be str, not bytes
• Multiple errors stemming from movie.py (Fix: Only read frame info in SWF.parse when decompression occurs #31
  )
  -- Error -3 while decompressing data: incorrect header check
  -- ValueError: read length must be non-negative or -1
  -- unpack requires a buffer of 1 bytes
  -- TypeError: ord() expected a character, but string of length 0 found
  -- negative shift count
