PR Title:

Bugfix: Allow Injection of Any PSR Cache Interface

Description:

This PR introduces a fix to allow injection of any PSR-compatible CacheInterface, enhancing flexibility for users of the MobileDetect library. It also addresses an issue where cached values that return false or null could lead to unintended behavior.

Key Changes:

• Switched from a specific cache implementation to the more generic CacheInterface.
• Adjusted logic for handling cache results that could return falsy values.

Testing:

• Verified with multiple cache interfaces to ensure compatibility.
