Bus scanning, secondary addressing, fixed data responses, wireless M-Bus decoding and a full CLI.

Added

  • Bus scanning. Client.ScanPrimary sweeps a range of primary addresses. Client.ScanSecondary finds meters by secondary address with a wildcard search that fixes the identification number one BCD digit at a time.
  • Secondary addressing. Client.SelectSecondary points address 0xFD at one meter and Client.ReadBySecondary reads it, for buses where primary addresses were never assigned.
  • Fixed data responses (CI=0x73). They decode into the same DecodedFrame with one record per counter, so every matcher and query works on them unchanged.
  • wmbus package: decode-only wireless M-Bus per EN 13757-4 and OMS. Frame format A and B with CRC verification, transport headers with CI 0x72, 0x7A and 0x78, and security modes 0, 5 and 7. Wired and wireless records are the same type.
  • mbusctl CLI with scan, read and set-address subcommands over TCP and serial, and a -json output mode.
  • Runnable godoc examples for decoding, the record query API, scanning, secondary reads and wireless decoding.

Fixed

  • VIF extension types no longer collide with primary VIF types in Unit.Type. Error-flags records used to match MatchType(VIFVolume). Extension types now carry a 0x100/0x200 offset, named by the new VIFExt constants.
