Documentation update

    The DE `protocolVersion` is used to select the appropriate protocol decoder at the receiving ITS-S.

      For TS 103 724 V2.1.1, the value of the DE `protocolVersion` shall be set to `1`.

    The DE `messageID` shall be harmonized with other V2X message identifier definitions.

      For IMZM, the DE `messageID` shall be set to @todo `imzm(15)`.

      For IMZM, the DE `messageID` shall be set to `imzm(15)`.
