zucbor: Deterministic and Secure CBOR Encoding and Decoding

Description

Encodes R values as Concise Binary Object Representation (CBOR, RFC 8949; Bormann and Hoffman (2020) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.17487/RFC8949")}) and decodes CBOR into ordinary R vectors and lists. Decoding checks the whole input against configurable depth, size and item limits before any R object is built, so untrusted input from network peers and devices cannot drive large allocations. Encoding is deterministic: identical R objects always produce identical bytes. Uses a bundled copy of the 'TinyCBOR' library (https://github.com/intel/tinycbor), so no system library is required.
