In moshi 1.10.0 proguard rules are generated automatically by code gen. This creates many files one for each annotated class.

This started to cause R8 to have a significant performance issue. Sometimes resulting in this error message.

> Task :app:minifyReleaseWithR8
R8: Library class android.content.res.XmlResourceParser implements program class org.xmlpull.v1.XmlPullParser
Too long with no output (exceeded 10m0s): context deadline exceeded

Here is a build scan of Moshi 1.9.3 on a sample project https://scans.gradle.com/s/fxq27ota2pdpo/performance/execution where R8 only takes 9.565s

And here is the same project with Moshi 1.11.0 https://scans.gradle.com/s/3v3kxnwz6wp7c/performance/execution where R8 takes 11m 41.181s
