Scalameta tree pretty printer

Pretty printer for Scalameta trees using Paiges.

Improves the built-in Scalameta pretty printer (Tree.syntax) with the following properties:

• [X] Correctness: Handling of precedence rules, inserting parentheses where necessary.
• [ ] Trivia Preserving: ability to preserve comments and other syntactic elements when doing tree transformation.
• [X] Line Wrapping: large expressions don't appear in a single line with hundreds of columns.
• [ ] Better Performance

The end goal of this project is to enable a more powerful refactoring API for Scalafix. Currently, Scalafix rewrites are implemented using a fairly low-level token API, which is error-prone.
