Proposal: A General Purpose Tree Viewer/Editor

[glyh]

Basically fern.vim

This component should be extensible, and can have different styles(e.g. git-branch like, file-tree like, lisp like)

I'm not quite sure whether this should be built-in, but I'm pretty sure this useful, just like pickers.

Usecases:

• File explorers for both local and remote machines, like nerd-tree
• undo-trees like undotree
• git branches, commits
• symbol-viewers like symbols-outline.nvim
• syntax-tree of current-file like nvim-treesitter/playground
• TOC viewer for markdown
• Structural editing/inspecting for serialized data formats, e.g. JSON, YAML, EDN

I believe there was discussion before about adding a tree tui widget.

@kirawi Can you give a link to that issue?

@keeslinp I think this one is different because it's more about UI.

OK, I'll close this because this is duplicate.
