Define treesit-font-lock-level as buffer local

[Vincenzo Pupillo]

Ciao,
I use tree-sitter for different languages, for some of them I prefer font lock 
level 3, for others I prefer level 4. 
treesit-font-lock-level, however, is not defined as buffer local and so there 
is no elegant way to have 
different levels for different languages. 
Would it be possible to define treesit-font-lock-level as a buffer local?

Thank you.

V.
