add TastyUtil #512
Description
- jackson-module-scala tries to process only Scala classes because when it tries to introspect Java compiled classes, it can cause issues because of the different naming conventions in the 2 languages
- this code relies on ScalaSignature/ScalaLongSignatire annotations added to Scala classes
- these annotations are not added to Scala 3 (Dotty) classes
- the TastyUtil looks instead for the .tasty files that are added to Scala 3 jars (alongside the .class files)
