[Flutter] Use FilterQuality.medium instead of FilterQuality.high

[spydon]

Regardless of the names, FilterQuality.medium actually almost always gives a better rendering output than FilterQuality.high, except when you need to scale up a lot, which I don't think is the case here.

I think this is the only place that needs to be changed:
https://github.com/EsotericSoftware/spine-runtimes/blob/4.2-beta/spine-flutter/lib/spine_flutter.dart#L140

I could provide a PR, but seems like more effort to sign the CLA etc than someone internally just doing that one-liner.

I'll happily add this manually. I wonder if we should make it configurable though. What do you think @spydon ?

[spydon]

Sounds like a good idea, that's what we did in Flame, but defaulting to medium. :)

Fixed in the latest releases. You can configure it via Atlas.filterQuality. Default is now medium
