fy_is_uri() is missing '#'. it is part of ns-uri-char in yaml 1.2.2, so valid tags fail today:

$ printf -- '- !<tag:example.com,2000:app/foo#bar> x\n' | fy-tool --testsuite -
stdin:1:33: error: missing '>' uri terminator
$ printf -- '- !foo#bar x\n' | fy-tool --testsuite -
stdin:1:7: error: invalid tag terminator

with the patch:

=VAL <tag:example.com,2000:app/foo#bar> :x
=VAL <!foo#bar> :x

!<foo #bar> x still errors, the space ends the uri and # starts a comment. %23 already worked, only the literal char was missing.

added parse_bug_tag_uri_hash to test/libfyaml-test-parse-bugs.c: four valid inputs with the expected tag (verbatim, !<foo#>, local !foo#bar, %TAG handle + !e!x#y) and !<foo #bar> x as invalid. it fails before the change and passes after. full ctest: 4898 passed, 0 failed (18 disabled as before). yaml-test-suite --testsuite output is byte-identical before and after on all 402 cases, and yaml-reference-parser emits the same events as above.

found it while diffing yaml implementations against each other for an eval i'm building.
