tree-sitter shared libraries can't have lib prefix

[CarsonEllsworth33]

When I clone and build grammars I have to rename the shared libraries from libtree-sitter-<lang>.so to tree-sitter-<lang>.so otherwise cffi can not find the functions to execute.

you can get around this by using the keyword fn-name obv, but it would be nice for the function to look for the prefix of lib and remove it automatically so it doesn't need to be done every time.
