Need another tinfl_decompress_ function about miniz HOT 2 OPEN

Ok, I'll see what I can do for the next release.

Harris, I don't mean to intrude but I have work with Miniz recently and I can 
share my experience with streaming data in it.

If you don't mind reading a bit of Rust code (similar to C++), take a look at 
https://github.com/williamw520/rustyzip/blob/master/src/rustyzip_lib/deflate.rs.

Look at the following methods in particular,
compress_stream, compresses data from a generic Reader to a Writer.
compress_upcalls, compresses data from input callback and output callback.
decompress_stream, decompresses data from Reader to Writer.
decompress_upcalls, decompresses data with input, output, and rest callbacks.

All these use the low level tdefl_compress and tinfl_decompress functions.  
Hope these help.
