Migrate particlefile output to tabular (via Parquet)

[VeckoTheGecko]

We are looking to migrate out particle file output to a tabular output using Parquet. This will have the following benefits:

• simplifying the particlefile.py module as particle positions can now be trivially appended
• simplify analysis of trajectories (since trajectory output isn't fundamentally n-dimensional, storing it in Zarr can be quite confusing for those doing post-processing or analysis)
• easier integration into other trajectory analysis tools
• making it easier to implement other parcels features down the line (e.g., restarting simulations)

Tasks:

• Base implementation (no ability to call pset in a loop, no restarting simulations)
• Documentation
• Additional features
• Conversion tooling: Parquet to CF-trajectory compliant Zarr
  • As part of this migration, we can build tooling that converts this Parquet output to CF-trajectory compliant Zarr output (i.e., as a post-processing step) allowing for users to keep their existing scripts analysis scripts if they'd like, and for easier integration into packages like Trajan.

Additional things to consider:

• How does parquet scale up to large outputs? (potentially useful link: https://arrow.apache.org/docs/python/getstarted.html#working-with-large-data )
• How does integration of this output with other tools (e.g., https://github.com/oj-tooth/lt_toolbox ) in the ecosystem look like

Previous attempt: #1399

FYI @oj-tooth

Keen to discuss further if people have ideas on what this should look like.
