[FEATURE REQUEST] Easier method to read request params

[Israel-Laguan]

The current way to read request params it's like this:

https://github.com/thruster-rs/Thruster/blob/d80cf36ca3f8f40324dc5325a3c150aa5c833953/thruster/examples/mutable_state.rs#L37-L45

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 request params, for example a HashMap context.params() so users can .get("paramKey") related to a param like in GET /posts/:id
• Add a new example using it, or include it in an already made example.
