porcupine/plugins/langserver.py:789: error: Argument 1 to "addFilter" of "Filterer" has incompatible type "HackFilter"; expected "Union[Filter, Callable[[LogRecord], int]]"

HackFilter is a class that has a filter() method but doesn't inherit from anything. This should work, according to docs: "You don’t actually need to subclass Filter: you can pass any instance which has a filter method with the same semantics." https://docs.python.org/3/library/logging.html

Callable[[LogRecord], int] seems wrong. The imlpementation basically does self.filters.append(filter). Does it really handle callables and objects with a .filter() method everywhere where it uses self.filters?
