Use starlette-cramjam compression middleware

right now we have to install brotli dependency and use default middleware which is not customizable (ref #268)

I think we could create a simple middleware which support zlib and brotli using pyrus-cramjam and also add a path filter as we've done in #297

Are these two different issues? One to change the compression implementation from the defaults to a third party package, and a separate one to add a path filter to the middleware? Seems like you could subclass the existing middleware to add a path filter without changing the compression implementation?

@kylebarron it's kinda 2 issues in one

1. we need a custom middleware to filter based on path or media type
2. we need one solution that could support brotli and zlib

Creating a brand new middleware based on pyrus-cramjam will let us do what ever we think is good ;-)

I started something over https://github.com/developmentseed/starlette-cramjam but for now I'm blocked at making streamed response working!
