Add CBOR reading utilities

The reading is very simplistic, parsing individual tokens. The larger
structure of the data would be interpreted by the client. There is a
function to skip over a more complex items but it doesn't extract any of
the data and just moves past it in the input buffer. Skipping supports a
limited depth of nesting and fails if the nesting goes too deep.

A fuzzer is included. As are a set of tests that no doubt could be
expanded upon.
