RemovedUnused not working if -Wconf:any:warning-verbose

-Wconf: options were added in Scala 2.13.2. warning-verbose includes category and location in logging output, which is apparently being parsed to find the unused imports.

Thanks for the report! For the record, https://github.com/scalacenter/scalafix/pull/1163 recently reduced false negatives when checking against scalacOptions in RemoveUnused.

Regarding the usage of -Wconf: from my understanding it's only a way to filter/change the logging level of compiler warnings, but it does not enable them as such. Could you post an example of code / scalacOptions for which you would expect RemoveUnused to run?

@jeffrey-aguilera are you still running into that? thanks!
