This is the test set for CBOR encoding.
This is largely complete for the implemented.
A few more things to do include:
- Add a test for counting the top level items and adding it back in with AddRaw()
- Run on some different CPUs like 32-bit and maybe even 16-bit
- Test the large array count limit
- Add the CBOR diagnostic output for every expected
