Geometry Nodes: Reuse audio readers for sound frequency sampling

Browse source 
Reuse AUDASPACE readers between uncached Sample Sound Frequencies windows
instead of creating a new reader for every window.

Readers are acquired through a small cache associated with the current
`bSound` runtime generation. An RAII lease automatically returns readers after
use, while failed seek or read operations discard potentially invalid readers.

The cache retains at most two idle readers. When all cached readers are in use,
a new reader is created outside the cache lock instead of making concurrent
evaluations wait.

Cached samplers and their reader cache remain alive for evaluations already in
progress when a sound is reloaded or freed.
