Subassets on Numeric Assets

Motivation

There is no particular reason to disallow subassets on numeric assets and there is a strong community demand to be able to do so (see for example https://github.com/mikeinspace/Glyphs/blob/main/README.md)

Design

Currently the validate_subasset_parent_name function checks that the parent asset is not numeric: https://github.com/CounterpartyXCP/counterparty-core/blob/master/counterparty-core/counterpartycore/lib/util.py#L238 This is the only place where this check is performed.

A protocol change allow_subassets_on_numerics will be added in the protocol_changes.json file. From this block on, the verification will be removed from the function validate_subasset_parent_name.
