Support base64 strings in getBinaryValue() for CBOR and Smile

[hherman1]

Adds support for deserializing base64 strings as binary. Elasticsearch returns base64 strings
for binary fields, not native binary.

Sounds reasonable, although I'd probably have to check if this is similar to what other backends do (I think ParserBase has something similar already).
It would be nice to also have a unit test showing simple usage and verify correct operation?

But one request: could you rebase this against 2.13? Master branch is for Jackson 3.0 which is still some ways off, so this change would make sense for 2.13 which will be released much sooner.

Thanks! I created a bit bigger patch to also support this for Smile, and for alternative access method, and for 2.13 branch.

Thanks so much! Sorry I dropped this, but glad we’ll be able to remove this code from our code base! :)

@hherman1 No problem, was easy to add just needed to have a bit of time :)
