Scanner component improvements in Retool Mobile

An improved version of the Scanner component for Retool Mobile is currently in private beta on Retool Cloud and on Self-hosted Retool 3.173.0 or later.

This includes:

• The ability to restrict or select from multiple barcode symbologies to scan.
• The ability to select between Manual or Automatic scan modes.
• While scanning from the native app, there is a visual indication of what is being scanned (a bounding box) when hovering over a barcode, as well as a checkmark when a scan is successful.
• Scanner V2 does not have the autoClose property.
