   Most API's defined in miniz.c are optional. For example, to disable the archive related functions just define
   MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO (see the list below for more macros).

   * Low-level Deflate/Inflate implementation notes:

     Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or
     greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses
     approximately as well as zlib.

     Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function
     coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory
     block large enough to hold the entire file.

     The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation.

   * zlib-style API notes:

     miniz.c implements a fairly large subset of zlib. There's enough functionality present for it to be a drop-in
     zlib replacement in many apps:
        The z_stream struct, optional memory allocation callbacks
