Better support for parsing date-related data types from ClickHouse

- Support parsing timezones out of `DateTime` and `DateTime64` types,
  and add support for `Date` type.
- Switch to using `nom` for more robust parsing of these types.
- Fix bug in block concatenation, where we concatenated rows but didn't
  update the contained row count. Add regression test.
- Add a new USDT probe for data packets specifically, with size and
  column names / types
