Missing support for BigQuery data types with schema check

[janet-can]

From the community Slack soda-core channel:

I was trying schema checks against bigquery using their types in bigquery:

      warn:
        when wrong column type:
          col1: INT64
          col2: TIMESTAMP

I got

      schema [WARNED]
        column_type_mismatch[col1] expected(INT64) actual(INT64)
        column_type_mismatch[col2] expected(TIMESTAMP) actual(TIMESTAMP)

If I use integer instead of INT64 col1 passes. Haven't been able to pass the check for col2. According to this, these types are supported.

Are we missing support for data types?
