Plugin will apply setup if wasn't applied on existing files, added more options.

[ml-212]

Hi, first of all, I'm glad you've made this plugin, there aren't many plugins for folding comments.

I've had some issues with LazyVim due to LazyVim's setup default options, I've managed to make it work with default options.

I have had issue with hiding comments with more buffers, applying setup with function calls fixed this for me, I'm not sure if it was a me problem or LazyVim's defaults.

While working on plugin I've added some options, new options:

• enable_notifications            > Notify user of language change. (I wasn't sure if plugin does it's job due to LazyVim setup)
• using_folke_lazyvim_setup > Compatibility with Folke's LazyVim setup.
• apply_to_new_buffer           > Apply setup to new buffers, and hide/reveal.
• apply_on_buffer_change    > Apply hide/reveal on every buffer change. I must admit, this might not be the best way for applying setup for already existing buffers, but it does the trick.
