zlib sources removed from this tree
This, for whatever reason, breaks std::fs exception handling. All remaining external projects will be moved to use this approach soon. This is to prepare it for more new libraries which would otherwise make the tree grow even further.

-/* ===========================================================================
- Decompresses the source buffer into the destination buffer. *sourceLen is
- the byte length of the source buffer. Upon entry, *destLen is the total size
- of the destination buffer, which must be large enough to hold the entire
- uncompressed data. (The size of the uncompressed data must have been saved
- previously by the compressor and transmitted to the decompressor by some
- mechanism outside the scope of this compression library.) Upon exit,
- *destLen is the size of the decompressed data and *sourceLen is the number
- of source bytes consumed. Upon return, source + *sourceLen points to the
- first unused input byte.
-
- uncompress returns Z_OK if success, Z_MEM_ERROR if there was not enough
- memory, Z_BUF_ERROR if there was not enough room in the output buffer, or
- Z_DATA_ERROR if the input data was corrupted, including if the input data is
- an incomplete zlib stream.
