// getContentType returns one of fieldsV1InvalidOrEmpty, fieldsV1InvalidOrValidJSONObject,
// fieldsV1InvalidOrValidCBORObject based on the value of Raw.
//
// Raw can be encoded in JSON or CBOR and is only valid if it is empty, null, or an object (map)
// value. It is invalid if it contains a JSON string, number, boolean, or array. If Raw is nonempty
// and represents an allowable value, then the initial byte unambiguously distinguishes a
// JSON-encoded value from a CBOR-encoded value.
//
// A valid JSON-encoded value can begin with any of the four JSON whitespace characters, the first
// character 'n' of null, or '{' (0x09, 0x0a, 0x0d, 0x20, 0x6e, or 0x7b, respectively). A valid
// CBOR-encoded value can begin with the null simple value, an initial byte with major type "map",
// or, if a tag-enclosed map, an initial byte with major type "tag" (0xf6, 0xa0...0xbf, or
// 0xc6...0xdb). The two sets of valid initial bytes don't intersect.
