Otter v2: A high performance caching library for Go

Today I'm excited to announce the release of Otter v2 - a high-performance caching library for Go.

Otter v2 has been almost completely reworked since its first release to provide a richer API and new features while maintaining high performance.

Key Improvements:

- Completely rethought API for greater flexibility.

- Added the ability to create a cache with any combination of features.

- Added loading and refreshing features.

- Added entry pinning.

- Replaced eviction policy with adaptive W-TinyLFU, enabling Otter to achieve one of the highest hit rates across all workloads.

- Added HashDoS protection against potential attacks.

- The task scheduling mechanism has been completely reworked, allowing users to manage it themselves when needed.

- Added more efficient write buffer.

- Added auto-configurable lossy read buffer.

- Optimized hash table.

- Test coverage increased to 97%

I hope this library will prove useful to some of you! :)
