[Feature]: Support of pg_analytics

[phyk]

What problem does the new feature solve?

When trying to combine data ingested into Postgres through timescaleDB and data in a s3 storage, it is currently slow and cumbersome to load the data from the s3 into postgres.

What does the feature do?

It allows for pg_analytics and timescaledb to coexist in a postgres database, to allow both extensions to work at the same time.

Implementation challenges

Currently, the two extensions clash due to both extensions defining the time_buckets function (paradedb/pg_analytics#150)

To the Timescale folks -- pg_analytics is now PostgreSQL licensed, so you are free to host it as you wish :)

Thanks for suggesting it @phyk.

The time_bucket function is the core function that most of the materialized views depends on,
can pg_analytics just skip its own time_bucket function and use the Timescaledb time_bucket function in case the extension already exists?
