v0.5.0

API Changes:

• The NVM secondary cache has been moved to a separate package: https://github.com/Yiling-J/theine-nvm.

Enhancements:

• Reduced Set allocations, making Theine zero allocation (amortized).
• Improved read performance slightly by utilizing a cached now value.
• Fixed race conditions in cost (weight) updates that could cause inaccurate policy cost.
• Added benchmarks for different GOMAXPROC values in the README.
