v0.0.23 Bug and usability fixes, but "modify" transform has issues

• Fixed bug in Jolt Sort.
• Usability
  • Better Exceptions thrown when parsing a Json
  • Ability to specify your own ClassLoader to lookup Transform classes

Do not use this release if you use the "modify-beta" transform.

• More Functions for the "modify-beta" transforms, but now some are broken
  • array "avg"
  • toBoolean
  • size
  • toString()
