Fabric adapter doesnt work with default cents_to_dollars macro (#43)

Using dbt-fabric adapter, trying to run dbt build fails with the
following error:

('42000', "[42000] [Microsoft][ODBC Driver 18 for SQL Server][SQL
Server]Incorrect syntax near '::'. (102) (SQLMoreResults)")

Adding a fabric specific macro (code supplied in this PR) for the
cents_to_dollars macro fixes this.
