Middleware addition is broken on sanic 22.12.0+

[Zerogoki00]

In sanic 22.12.0 they changed the internal structure of app's middleware collections (request_middleware, response_middleware)

Look at this commit: sanic-org/sanic@2abe66b
Now they don't store pure middleware functions there but instead they use Middleware class for each of them.

It still works somehow but looks like middleware order is broken and other unpredictable bugs may occur.

Why don't you just use register_middleware method as suggested in docs? (https://sanic.dev/en/guide/basics/middleware.html#attaching-middleware)

Please take a look at my pr which fixes it: #93
