[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
