Add dynamic vars, binding support, and exception support

[jeaye]

This also includes a complete re-format of the code, using clang-format. I don't like how it looks, but clang-format can't get any closer to what I want without patching. At least it's consistent.

This fixes #48 and the broken CI jobs, too.

Also, @Samy-33 included some initial support for the lein-jank plugin he's building, followed by some changes to improve jank support on Apple M1 hardware. :heart:
