uint-zigzag 0.2.1

Uint is a convenience wrapper for zig-zag encoding integers to byte sequences. This allows better compression since the majority of numbers are quite small resulting in 1 or 2 bytes in the most common case vs 4 for 32-bit numbers or 8 for 64-bit numbers. This also permits the user to not have to think about which integer type is the most efficient to compress.
