Add open/closed range arguments for incremental

[steinitzu]

Description

This allows configuring whether the incremental range is open or closed on both sides (start/end value).
Translates to changing the operators between > | >= / < | <= in sql database source and in incremental filtering.

Default is start_range=closed and end_range=open, meaning the exact initial value is included and the exact end value is excluded.
With start_range=open you get WHERE cursor > last_value instead of >=.
With end_range=closed you get ... cursor <= end_value so non-overlapping chunks are still possible without the start_value deduplication logic.
