[Feature request] Add filter for table exclusions

Some plugins tend to generate large tables with data that are beyond the scope of reasonable exports. Caches, logs, hash lists etc can on some sites take GBs in size. Exporting these are pointless, time and data consuming and is a waste of resources in most cases.

Please implement something like apply_filters( 'ai1wm_exclude_tables', []); which a developer could use to define a list of tables that are intended to become part of backups or migrations.
