Support for ["accept-encoding"] = "identity"

I ran into a problem with this proxying OpenAI because they use brotli encoding, and the proxy was serving through the encoded binary data - which means that any future features to mess with the content wouldn't work, refs #5

I found that this fixed the problem:

diff --git a/asgi_proxy/__init__.py b/asgi_proxy/__init__.py
index 98ab369..3e7dc43 100644
--- a/asgi_proxy/__init__.py
+++ b/asgi_proxy/__init__.py
@@ -17,6 +17,8 @@ def asgi_proxy(backend, log=None):
         # Replace host header
         headers["host"] = backend_host.encode()
 
+        headers["accept-encoding"] = "identity"

Maybe this should be another option to the def asgi_proxy(backend, log=None) function.

I'm just going to default to this for the moment - it's the only way I can get OpenAI proxying to work.
