v0.5.0

Yanked: This release incorrectly detected device changes. Use 0.5.1+.

This release removes DirConcurrency and related methods.

Parallel directory reads are now automatic and mandatory, but the inner loops — reading/filtering the contents of those directories — are now executed serially (within each parallel thread), greatly reducing the number of concurrently open file handles and subsequent risk of hitting ulimit ceilings.

The file collision (uniqueness filters) have also been greatly improved, further reducing the number of syscalls and overall search times.
