Bump OAN + add OAN_UID_AUTOCONF top-level option

Phase 1 of UID autoconfiguration lands in OpenAudioNetwork behind the
new OAN_UID_AUTOCONF flag (default OFF). Mirror the option here so
the parent build can propagate it; bump the submodule pointer to pick
up the new structs, algorithm, and tests.

See Docs/proposals/uid-autoconfiguration.md and -impl.md.
