custom_begin_buffer uses new functions to identify which files to treat as code
implement custom_render_buffer which uses tree sitter data to color tokens
- identify buffer language
- custom_begin_buffer sets up necessary tree sitter state, and kicks off a parse task
- custom_end_buffer cleans up tree sitter data and kills async parse tasks
- tree_sitter_parse_async/__inner uses tree sitter api to get a tree of the buffer's code and stores it on the buffers managed scope
- tree_sitter_write_tree prints tree to a special *tree* buffer
- use new build scripts in 4coder project
