also calculate key for temporary message, keep initial leadingSeparator if it was passed true in decode() and decodeLastData(), use empty condition messagename for referencing scan result, added MessageMap::getScanMessage(), do not poll for scan message, store derived scan message by key only, removed unnecessary minIdLength determination
