Transformation fail with can't create mutable bitmap with Config.HARDWARE in Picasso 3

Using: Picasso com.squareup.picasso3:picasso:3.0.0-SNAPSHOT Pixel 2, Android 9

When trying to use a transformation, I am running into the following issue:

    java.lang.RuntimeException: Transformation rounded(radius=140.0, margin=0.0) crashed with exception.

Using a config or the default result in the same issue.

Sure. Perhaps we have to expose it since, presumably, Palette will need software bitmaps.
