Allow artifact stats to be configurable

[eps1lon]

Not all projects are concerned with gzip sizes of artifacts.

Not sure if this is the right issue but I'd be interested in tracking arbitrary values. For example tracking benchmark results or lighthouse scores. So far it looks like I can only configure files as artifacts and it automatically assumes I want to track their size.

@eps1lon This is something I'm definitely interested in for Build Tracker!

That being said, it's a pretty big undertaking to think through and not something for the 1.x release. Many moving pieces that I can go into detail with if you'd like to contribute 😄

I have to figure out the whole self-hosting story first. That's a pretty big adoption hurdle compared to solutions that provide the server. But hearing that this is in the scope makes me more motivated to figure it out.

For the graphs, I noticed that Brotli is the default size type. We don't currently use Brotli so we would like the graphs to default to using gzip instead. Is this an easy change to make?

I noticed we have a sizeKey in Redux state. that defaults to ''. Changing that to 'gzip' didn't seem to do anything 🤔

The default currently goes to whatever is alphabetically first and can be changed with toggles in the drawer. I think a config option to set default would work.

Related to this: I would love to see support for passing a custom quality level to Brotli. (We use the maximum quality level—11.)

Do you think we could support something like that?
