3.1.0

• Added a new "Batch Size" input configuration parameter to allow importing assets in batches. This should reduce memory usage for large asset imports.
• Removed the "Since" input configuration parameter. This parameter was only used on the first import of data. The existing "Search Filter" input configuration parameter can be used to limit results if needed.
• Added new "_splunk_event_ts" and "_splunk_ingest_ts" attributes to imported assets.
• Set the event time associated with imported assets to the created_at or updated_at asset timestamp depending on the configured sync type.
• Use the built-in KV store to store checkpoints.
• Upgraded application dependencies.
