Add per collection-index use_indexer_date_filter option

[VladimirPress]

Description

Adds a new per collection-index configuration option use_indexer_date_filter.
When enabled for a collection, pywb forwards from and to date parameters to the indexer, if present.
This shifts date filtering to the indexer, reducing pywb CPU and memory usage, preventing OOM conditions, and lowering network traffic.

Unfortunately, I could not find an appropriate section in the documentation to add this parameter description.

Motivation and Context

This feature allows heavy date filtering to be offloaded to the indexer, which prevents pywb server overload and high memory usage for large collections.

Screenshots (if appropriate):

One small request: can you rename it to use_remote_date_filter? in pywb, 'indexer' can mean a lot of things, this is specifically for passing the from= and to= date queries to the remote index source (cdx server).

Done.
