Set Accept-Ranges: none header when compressing responses

[palant]

What is the problem your feature solves, or the need it fulfills?

When adjusting response headers, ResponseCompressionCtx will currently remove the Content-Length header as the old header does not apply. A potentially present Accept-Ranges: bytes header is left untouched however, even though ranged requests no longer make sense.

Describe the solution you'd like

Call resp.insert_header(&ACCEPT_RANGES, HeaderValue::from_static("none")) when compressing. This will both overwrite any existing Accept-Ranges header and explicitly indicate to the client that ranged requests are unsupported.

Describe alternatives you've considered
