Enqueue Feature, TTL fix, Dependencies update, Improve tests

• Add enqueue feature. This was previously an issue because a lot of method calls at the same time would trigger the original method. Now, the original method will just be called once.
• TTL fix: In non lazy mode, the TTL was treated as milliseconds. Fixed to seconds.
• Updated all the dependencies to newest versions.
• Improved tests
• Switched CI to Github Actions
