23255:Bank Reconciliation import

Either the file name or the `CSVMap/Name` is too generic. This map describes a particular CSV file format for importing bank reconciliations; there will most assuredly be others.

@shackbarth - where is a good place to put standard CSVImp atlases? `foundation-database/public/tables` is not right for a couple of reasons. OTOH, I don't think we have any more of these yet.
