- Implement scion_as_to_decimal() function in both add-as and add-as-batch scripts - Automatically converts SCION AS format (ISD:AS:Instance) to decimal when in BGP range - Handles both ISD:AS:Instance format and colon-separated hex format - Follows SCION AS numbering specification from https://github.com/scionproto/scion/wiki/ISD-and-AS-numbering
