Allow raw plot data to be downloaded directly to CSV

[DanSava]

Users of Everviz (which is developed on top of Webviz) have expressed the desire to have the ability to download raw plot data directly to CSV and not as a zip file. Would it be possible to have an option between ZIP and raw CSV?

This is definitely possible 👍 We actually started with .csv, and moved to .zip when there were (sometimes) need of downloading large files and/or multiple separate files.

Giving the option to plugin authors to define zip/csv/others(?) sounds reasonable.

We might, if possible, want to also look into moving away from using data-uri: in the implementation, and instead send the files directly with flask (the tricky part here could be that the data to be downloaded generally is not static, but "filtered"/selected by the user, and therefore "created" on demand and depends on the state in the front-end...might be some ideas here). Alternatively, if not prioritized now to move away from data-uri:, we could for now document what roughly the file size limit is (when using data-uri:) to plugin authors.

That is an interesting idea but would it be possible to solve it in a different issue? If that is the case I have an implementation suggestion in #71

Yes, that could be a separate issue and PR.
