Crash if original request is ASGI request

[FMiranda97]

I get a crash when using ASGI. This line fails to convert since ASGIRequest.environ does not exist.

django-middleware-fileuploadvalidation/django_fileuploadvalidation/modules/converter.py

Line 62 in 761518c

sanitized_request = WSGIRequest(original_request.environ)

Sorry for the long delay! Working on it!
