Allow changing the upload server

[MojangPlsFix]

It would be nice to change the upload server to a self-hosted one like in spark.
This benefits bigger servers that must be GDPR-compliant and minimize internal server data shared with third-party services.

I'll take a look at this at some point, but if you block requests from your minecraft server to my upload server, it should write the profiling data to your local machine. You then should be able to open the file at https://o.tas.sh, which will show you the results without uploading the file to the server.

Not an ideal experience, but if you're having problems with GDPR, this might work as a stopgap.
