* cbor: allow user to control nesting
- Make the default read/write entrypoints allow infinite nesting.
- Add {read,write}_nested() entrypoints that allow the crate user to
control the depth of nesting that's allowed.
- Along the way, convert the write[_nested] variants to return a
`Result<(), EncoderError>` rather than a bool. This exposes
more failure information (and forces the caller to take notice
of those tailures), and allows use of the ? operator.
* fixup: transmute error

* CBOR uses Vec for map internally
* remove BTreeMap from get_info
* rename cbor_map_btree and clean up cbor_array_vec
* destructure now takes Vec, not BTreeMap
* adds dedup in CBOR writer
* fail to write CBOR maps with duplicates
* CBOR interface refinements
* macro documentation for CBOR map and array
