Immediate panic when I put a custom syntax in ~/Library/Application\ Support/amp/syntaxes/

[mnemnion]

This is a syntax which I've used successfully with bat in the past.

Running amp after moving one .sublime-theme file into the indicated directory causes an immediate panic with this message:

thread 'main' panicked at 'attempted to leave type `linked_hash_map::Node<yaml::Yaml, yaml::Yaml>` uninitialized, which is invalid', /private/tmp/rust-20210325-49675-3ca9nq/rustc-1.51.0-src/library/core/src/mem/mod.rs:671:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

So I did, giving this

thread 'main' panicked at 'attempted to leave type `linked_hash_map::Node<yaml::Yaml, yaml::Yaml>` uninitialized, which is invalid', /private/tmp/rust-20210325-49675-3ca9nq/rustc-1.51.0-src/library/core/src/mem/mod.rs:671:9

note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

Leaving off the xterm commands which restore the terminal to cooked mode and so on.

This .sublime-syntax doesn't rely on any other syntaxes, it's self-contained, and works in Sublime Text and bat.

I can provide the syntax file if that would be helpful.

@mnemnion this seems related to: #205

@mnemnion thanks for the heads up! How did you go about installing amp? I can issue a new release for this, but want to make sure I'm covering your installation method.

Hi @jmacdonald I used Homebrew. I do have the Rust toolchain already, so if you want to give me a heads-up I'd be happy to test a release. Thanks!
