Add support for non-literal tag and simple value numbers from RFC9682

[rohanmahy]

Support non-literal tag and simple value numbers from RFC9682 Section 3.2

For example:

redacted_keys = #7.<TBD4>
TBD4 = 59 ; suggested value, to be assigned by IANA

rats_tags = #6.<rats_tag_nums>([ * bstr ])
rats_tag_nums = 60000..60002 / 60010 / 60020..60021
