Remove severity from diagnostic output

[NicholasLYang]

Hi, is it possible to remove the severity from the output, i.e. the Error: prefix? I find that for the related errors it looks a little out of place.

Thanks!

You can do this if you print out the error by hand and manually exit non-0, instead of relying on the return from main. This “Error” is added by rust itself, not miette.

There is currently no way to remove this from related errors, though
