[Web UI] Allow removing profiles

[codebymikey]

It would be great if there was a delete button for every profile to quickly delete it.

It would also be nice to have a purge profiles button.

When doing a lot of profiles, it often becomes a mess.

For now I manually delete the files from /tmp/spx but sometimes the wrong profile may be accidentally removed.

I'll implement this feature as a part of a full rewrite of the web UI.

sounds great! Hopefully, we can also export/import reports in the future, so they can be easily shared for debugging with someone else who has no direct access to my SPX web UI (but could easily spin it up on any other project e.g. using Herd Profiler without any extension mingling). see related #213

Thanks for this great project!
