Add tests

#23

Copied indent, font-lock, and movement tests from julia-mode-tests.el. As of now, 25/60 tests fail when using julia-ts-mode instead of julia-mode.

It would be better if we could somehow use julia-mode-tests.el without copying it into this repository. Maybe the best way would be to move julia-ts-mode to https://github.com/JuliaEditorSupport/julia-emacs?

Fixed a few tests and categorized the rest. Here are the 16/60 that still fail, categorized based on whether a tree-sitter-julia grammar issue is to blame. Tested using the v0.20.0 grammar.
