Valid TIDs are incorrectly rejected

3m3zm7eurxk26 is a valid TID but is incorrectly rejected.

This is because the formatter validates using Crockford's base32 but that's not the format atproto is using.

See https://atproto.com/specs/tid#tid-syntax for details and https://tangled.org/@slices.network/slices/pulls/4 for a fix.
