ITS/MFT decoder sends vector with certain errors details

An output vector<o2::itsmft::ErrorMessage> is added with information about
ChipStat::RepeatingPixel error details (at the moment, other errors may be added).
Each element of ErrorMessage is assigned as:
errMsg.id = chipID
errMsg.errType = ChipStat::RepeatingPixel (at the moment)
errMsg.errInfo0 = row
errMsg.errInfo1 = col
