Deprecated Python binding

[lmandrelli]

What's wrong ?

When you use the tree-sitter grammar with python, the current binding.c uses a depracated constructor:
Language(ptr) is deprecated since tree-sitter 0.22.0

Expected :

The library moved to a new architecture where you should use language specific packages.

Solution :

For the batch-tamarin project, to use a parser, I needed to precompile the grammar for each platforms and architecture, I replaced the deprecated function by the current way to do it :

src/grammar/tree-sitter-tamarin/bindings/python/tree_sitter_spthy/binding.c, at line 8

return PyLong_FromVoidPtr(tree_sitter_spthy());

should be replaced by :

return PyCapsule_New(tree_sitter_spthy(), "tree_sitter.Language", NULL);

and the src/grammar/tree-sitter-tamarin/bindings/python/tree_sitter_spthy/init.py should be rewritten as :

"Spthy grammar for tree-sitter"

from tree_sitter import Language
from ._binding import language as _language

def language():
    """Get the tree-sitter language for Spthy."""
    return Language(_language())

__all__ = ["language"]

This will completely fix the deprecated warning. At least, it worked for my package
