target-bigquery v0.12.0

New feature:
Infer BigQuery DECIMAL/NUMERIC or BIGDECIMAL/BIGNUMERIC data types from multipleOf in JSON schema.

• Decimal data types are more precise than FLOAT, can represent decimal fractions exactly, and are suitable for financial calculations. Learn more here.

• Caution: this is a breaking change, because some fields previously loaded as FLOAT will now be loaded as DECIMAL.

Change:
Bumped setuptools to version 60.3.1.
