v0.14.0

What's Changed

The library has been refactored to be a wrapper around golang.org/x/sync/singleflight instead of a fork. This change (#5) makes the implementation:

• Easily verifiable (direct delegation to original package)
• Easier to maintain (simpler upgrade path when original package adds generics)

The change is fully backward compatible - all existing code will continue to work as before.
