feat: Add Timeseries Collection Support

[massooti]

This pull request introduces support for timeseries collections in MongoEngine, addressing issue #2661. With the addition of a 'timeseries' option in the Document meta dictionary, users can now easily create and manage timeseries collections. This enhancement aligns with MongoDB 5.0's timeseries feature, providing better support for time-based data storage scenarios. Contributions welcome!

Closes #2661 (if applicable)
