Jemalloc issues on Apple Silicon macs

Forest is compiled with jemalloc as a default allocator. If you are having problems running or compiling Forest, use this checklist:

1. Make sure you are using an arm64 version of homebrew; this could be a problem one inherits when migrating from an Intel Mac to Apple Silicon: Stackoverflow example.
2. Make sure your default host is set to aarch64-apple-darwin via rustup set default-host aarch64-apple-darwin.
3. This could result in various errors related to the fact that you still have some of the libraries symlinked to /usr/local/lib from an intel Homebrew installation. The easiest fix for this is:
   • Remove the libraries in question from /usr/local/lib.
   • Add export LIBRARY_PATH=/opt/homebrew/lib to your bash profile.
   • Source the new bash profile.
