Function registerTags

Register dcbor's standard tags and every tag in ALL_TAGS into store (default: the global store), in the reference's order: date (tag 1) with its summarizer, then the 75 tags of this package.

Idempotent: a value already registered under the same name is a no-op, and a name already registered under another value moves to this package's value, as the reference's insert_all does. Tags 2 and 3 stay unnamed, as in the reference's default build; for the num-bigint registry call registerStandardTags(store, { bignum: true }) before this function.
