fix: remove CBOR

Using CBOR forces us to choose between #1271 and #1247. Our complicated
importing and bundling situation makes using this library very hard.

CBOR support has been undocumented, and we are not aware of significant
usage in the wild. Therefore, we do not consider this a breaking change.
To make our expectations clearer, this PR also marks MessagePack as
`experimental`.

We will improve our importing and bundling situation before
reintroducing CBOR via a plugin.

Closes #1271
