I can see there is still an issue with loading heex-ts-mode from 
elixir-ts-mode, but not quite sure how to
immediately resolve it. I will have a look in a couple of hours.

The problem is in the top of elixir-ts-mode.el: (require 
'heex-ts-mode) and then we call
(treesit-ready-p 'heex) in heex-ts-mode. I guess the intention 
with the
convention here was to only load the -ts-mode when the user 
explicitly requires, but it
breaks the way I called (require 'heex-ts-mode) from 
elixir-ts-mode.el.
