Update the measurements creation to use parquet/dask rather than arrow/vaex files

[ddobie]

To do:

• Update the docs to remove all references to vaex and arrow files
• Merge dependency upgrades

Notes:
The log files aren't displaying properly in the web interface. The interface can find the files, but not display them, e.g.

I realised that the measurement pairs parquet files don't need to be generated (in fact doing so breaks everything because they already exist). So there's a few changes that need to be made to the code (mostly done) and the nomenclature ("Generate parquet files" -> "Generate measurements parquet")

Screenshots that need updating:

• docs/using/genparquet.md parquet-files-available.png
• docs/using/genparquet.md generate-parquet-button.png
• docs/using/genparquet.md generate-parquet-modal.png
• docs/using/genparquet.md generate-parquet-notification.png
• docs/using/genparquet.md generate-parquet-files-log

Other things to update

• Update run config

Looks good. Just some minor typos and a suggestion to make a separate function to delete files or directories.

I've implemented the suggested changes. Also fixed a few minor bugs and warnings that I hadn't picked up the first time I tested it.
