Merged PR 2124: Denormalized Bank Transactions Mart

A very denormalized table that brings Bank Transactions Line Items, Bank Transactions and Contacts into a single table.

Building this because we need to show some data in a PBI report that needs data from all three tables and can't be joined in PBI.
