FUNCTION: V2gMsgDecoder
DESCRIPTION:
        1. Decode the V2GTP messages inside "msg" and save the decoded
           messages in ccs_exi_doc_DIN, ccs_exi_doc_ISO1, and ccs_exi_doc_ISO2,
           respectively.

        2. After decoding, V2gMsg_Process() could then use
           ccs_exi_doc_DIN, ccs_exi_doc_ISO1, or ccs_exi_doc_ISO2
           to deal with the corresponding Response messages, respectively.

PRE-CONDITION:
        1. msg_length > 0

INPUT:
        1. msg
        2. msg_length

OUTPUT:

        *V2GT_MSG_PROTOCOL_HIGHEST_PRIORITY: choose the one with the highest priority

    2. [To-do] Checking Major and Minor version
    3. The parsing method will not support those private protocols,
       such as "usr:tesla...," since "tesla" is 5 bytes but "din" and "iso" are 3 bytes.

    4. [To-do] If the target is selected as DIN," but there is no DIN.
               However, if EV and EVSE all support ISO, how to use ISO instead?
