Problem

xz_decompress reads the entire .xz file in one call. The entire file is stored in memory. Decompressing large files can lead to Out Of Memory errors.

Solution

Provide xz_decompress_with_options, similar to other _with_options API functions. Notably, this would allow passing an Options with a set memlimit. Then the user need not store the entire file in memory.

Similar to #49

blockreader.rs attempt to parse more of the XZ header

Attempt to parse more of the XZ header and block #0 header.
Unfortunately, I couldn't figure get this working entirely. Leaving
the code in place as it does function.
The intent was to compensate for lzma-rs reading the entire file
during xz_decompress. However, that's a larger problem, see
gendx/lzma-rs#110
