deny list based filtering

[dvdsk]

Text to be checked/linted is added to a lintreq. To determine whether text should be linted I check if it corresponds to an allowed highlight group using tree-sitter queries, a allow list based system:

For any tree-sitter subtree (parser:for_each_tree)
     iter over highlights (hl_query:iter_captures)
         add to lintreq if allowed hl_group

Some languages, such as latex, need text linted that is not highlighted. For this we need a deny list style operation.

Configuration must be language dependent
Instead of always running in allow list mode the event handler on_event should change to deny list mode depending on config

language dependent config

options:

• switch based on parser lang
• switch based on buffer lang (an autocommand?)
• switch based on file extension (see 25ec193)

deny list style on_event

split lintreq builder into allow builder and deny builder. Both still build into a lintreq

replaced with treesitter query based linting doing away with hl groups entirely
