There are two things here, one is about you creating a wrapper but
still surfacing the wrapped framework exceptions etc... I'd recommend
that you really make this a wrapper and shield the consumers from the
actual implementation details, this would allow you to swap or provide
different implementations in the future.

As for the legal aspects, in high level summary, you need to update
LICENSE file with this new dependency (face4j), list the jars under
that license, and provide the copy of the MIT license there. See [1]
for how other dependencies are listed. You might also need to update
the NOTICE file if there are specific notices in the face4j
frameworks. Note that, If face4j brings new transient dependencies to
PhotArk, you need to handle those as well.
