This pr refactors most tests that use RAV to use DRAV instead; this also has the nice effect of testing both the RAV and DRAV implementations at the same time w/o having to duplicate all of our AST visitor tests. Some tests rely on features that DRAV doesn’t support (mainly post-order traversal), so those haven’t been migrated. At the same time, `TestVisitor` is now a DRAV, so I’ve had to introduce a new `CTRPTestVisitor` for any tests that need to use RAV directly.
