MS UICC Low Level Access: string in ATR query response wrongly formatted

The ATR message is defined as follows:

  { "name"     : "ATR",
    "type"     : "Command",
    "since"    : "1.26",
    "query"    : [],
    "response" : [ { "name"   : "atr",
                     "format" : "string" } ] },   

But the string field given in the response is not encoded in the usual MBIM way of "offset+length", it is encoded as "length+offset" instead. in the same way as all the other arrays in https://docs.microsoft.com/en-us/windows-hardware/drivers/network/mb-low-level-uicc-access, so we cannot use the generic string type, we need a custom type like uicc-string or something like that.

added MEDIUM label

@Som_SP FYI

Hi @aleksm , I have changed it as per MBIM Spec to byte array and submitted a patch in MR156 along with cli option. Pls review the same.
