This release is mainly fixing a bunch of scope tracking problems that I uncovered while working on another project that made heavy use of it :) If you did not use it (you probably didn't) then this is not going to make a huge difference for you

- Fixes a bunch of scope tracking issues
- Exports symbols necessary to use the exported scopes, constants to signify types etc
- Drops a completely useless scope from the `TryStatement` node
  - I don't think this is a breaking change since the scope was incorrectly there in the first place; it could have not caught anything
- Fixed a few issues with error paths that would ironically lead to TDZ errors
- Fixed a problem in the code frame where the offset was incorrectly reported
- Fixed a potential problem with checking backreferences in regular expressions
