Compression rules. This works in combination with the `outbound rules` bellow. Basically what happens is:
1. We check if the user agent supprots compression via the `Accept-Encoding` header.
2. We prioritize `brotli` of `gzip`, and append the right extension (`.gz` or `.br`) and prepend `dist`.
`dist` is where all the pulic assets live. This is transparent to the user.
We assume all assets with those extensions have a `.gz` and `.br` version because of the build system we
have.
IIS then serves the asset applying the outbound rules.
3. If the final part of the file (`.ext.gz` or `.ext.br`) matches one of the `CompressedExtensions` `rewriteMap`, we
rewrite the `content-type` header
4. Based on the extension (`.gz` or `.br`), we rewrite the `content-encoding` header
