FR: Add support for time_bucket offset and origin parameters

[draisbeck]

The time_bucket function by default operates in UTC time - which has implications if you're attempting to to do daily time buckets with data from a specific timezone.

Per the timescale docs, the best way to adjust for this is with the the offset or origin parameters to the time_bucket function.

Hi @schlunsen, Is it possible to merge these changes to main. I really need this feature and I'd appreciate if you could do it.
