[10.0] Better parse camt groupped transactions (#131)

* correctly parse entries with multiple transactions Our bank does it. Care has been taken not to break cases where Ntry/NtryDtls/TxDtls isn't used: if any piece of information isn't found on these nodes, the matching information from the Ntry is used. Most often the entry has a sum or a summary and the transaction details are more precise and specific, so it makes sense to use their contents rather than its. * more complete unit tests for camt parser This checks the whole output data of the parser against its expected output. * add a test case that checks TxDtls decoding * special case for Ntrys without TxDtls * CO-12 - Date Import BVR * FIX tests * CO-1232 Fixed issues with CAMT parser tests
