Bare-clawed Unathi footstep sounds. (#18975)

This PR will add barefoot walking sounds for Unathi. Their claws will
make a clicky sound when they walk around. The sound files are
lightweight, and should be less than 75 kilobytes total.

The claw clicks are bespoke, sourced from a family dog and edited for
clarity and noise reduction.
The footstep noises beneath are from walk_indoor_barefoot.mp3 by
