Bit level parsers and combinators

Bit parsing is handled by tweaking the input in most macros. In byte level parsing, the input is generally a &[u8] passed from combinator to combinator until the slices are manipulated.

Bit parsers take a (&[u8], usize) as input. The first part of the tuple is an byte slice, the second part is a bit offset in the first byte of the slice.

By passing a pair like this, we can leverage most of the combinators, and avoid transforming the whole slice to a vector of booleans. This should make it easy to see a byte slice as a bit stream, and parse code points of arbitrary bit length.
