Fast test for URI containment

[jakebeal]

I sometimes need to check whether a given URI is likely to be in an ontology. Given that there are multiple legal prefixes, there isn't a simple way to check this without just looking up the term, which is costly when the term is not in the ontology.

Example of a current function for this including partial workaround:

def has_SO_uri(uri: str) -> bool:
    """Test if a given URI is in the ontology (effectively an exception-checking wrapper around get_term_by_uri)

    :param ontology: Ontology to check for term containment
    :param str: URI to look up
    :return: true if this is a URI in the
    """
    if not (uri.startswith("https://identifiers.org/SO") or uri.startswith("http://identifiers.org/so/SO")):
        return False
    try:
        tyto.SO.get_term_by_uri(uri)
        return True
    except LookupError:
        return False
