Integrate languagetool about prosesitter.nvim HOT 4 CLOSED

First hurdle, how to do async http req.
useing curl for http access (limits to linux/mac with curl install) (good enough for now)

hard coded path run

• add async curl call to example.com to checker
• pipe text into curl and call langtool
• add callback to parse langtool results

from prosesitter.nvim.

combine output of vale and language-tool after checking

• ensure language-tool extmark adding does not remove vale extmarks and viceversa
  - seperate extmark namespace, pass namespace to callback
• merge spell checking by vale and language server? Better alternative is to disable any spellchecking in vale if langaugetool is enabled/found

from prosesitter.nvim.

start languagetool server on boot

• figure out how to keep forked process running in parallel to vim
  • check if java exists
• start language-server with a hardcoded path

from prosesitter.nvim.
