v5.20

Fix:

• Wrong SIM card detection that checks hardware slots instead of inserted SIM cards.

Improvements:

• Backups can now be encrypted
• "Database Prefix" now supports minimum match counts, use case:
  Block 11199 only if at least two similar numbers exist in the database(e.g., 11122 and 11133)
• Show the last digits of phone numbers on the SIM picker instead of simply "SIM 1/2"

Changes:

• Dropped support for Forwarded Call(e.g., 111&222), removed it from regex presets and API options.
  It's a rare telco bug and can be blocked by regex \d+&\d+
