[FEATURE REQUEST] Easier access to read request headers

[Israel-Laguan]

The current way to check headers is in the line of

let header = context
  .hyper_request
  .as_ref()
  .unwrap()
  .request
  .headers()
  .get("Origin");

Which for a commonly used section of the request feels long.

An easier way to read the headers (like the context.content_type("application/json"); to set a custom outbound header) would lower the entrance bar for new people trying thruster for use as a server.

Request

• A method to access headers, for example a HeadersMap context.header() so users can .get("HeaderKey") or even context.header("headerKey"), for example to get header "Autorization" or any from http::header
• Add a new example using it, or include it in an already made example.
