No effort is made to convert the data types of the values in the cells.
The timestamps of the cells are converted to Python's isoformat.
The `timestamp_epoch` calculated timestamp field is naive. (i.e. based on
the local time of the system the parser is run on)
Raw output contains all cells for each column (including timestamps in
converted to Python's isoformat), while the normal output contains only the
latest value for each column.
The `timestamp_epoch_utc` calculated timestamp field is timezone-aware and
is only available if the timestamp has a UTC timezone.
The `timestamp_iso` calculated timestamp field will only include UTC
timezone information if the timestamp has a UTC timezone.
Raw output contains all cells for each column (including timestamps), while
the normal output contains only the latest value for each column.
