🔨 using input/output adapters for CBOR and MessagePack

Browse Source 
- You can now pass a reference to a vector to the to_cbor and to_msgpack functions. The output will be written (appended) to the vector. #476

- You can now pass an output stream with uint8_t character type to the to_cbor and to_msgpack functions. #477

- You can now read from uint8_t */size in the to_cbor and to_msgpack functions. An input adapter will be created from this pair, so you need to use braces. #478
