v1.7.0 dbt_quickbooks

PR #209 includes the following updates:

Schema/Data Changes

1 total change

Data Model(s)	Change type	Old	New	Notes
All models	source_relation column (when using a single QuickBooks schema)	Empty string ('')	<database>.<schema>	Full refresh required after upgrading.

Feature Updates

• Introduces the new (recommended) quickbooks_sources variable for more robust union data configuration. The old quickbooks_union_schemas and quickbooks_union_databases variables will still be supported. See the README for specific details.

Under the Hood

• Adds the fivetran_using_source_casing variable for case-sensitive destination support. When enabled, downstream transformations respect source casing to ensure consistent results. See the Additional Configurations section of the README for details.
• Updates partition_by_source_relation macro to conditionally include source_relation in partition clauses only when multiple sources are configured.
