[Feature] Update date_spine and staging filters

Describe the Feature

Currently, stg_amplitude__event is limited by these filters to reduce the number of records brought in.

These dates are also used in theint_amplitude__date_spine here.

At the time of creation 2020-01-01 made sense, but should we reconsider the default date as time goes on?

How would you implement this feature?

I was thinking we could limit by doing a date_trunc to the past X years instead of hard coding a date, so that way the beginning date isn't moving every day. There could be lots of other ways here, however.
