Create an api crate (maybe 2)

[ModProg]

Is your feature request related to a problem? Please describe.
I want to implement api queries in https://github.com/modrinth/theseus, and there are no "official" API bindings for modrinth to atleast use internally.

Describe the solution you'd like

1. Create a crate modrinth-api-types that holds all types used in the public modrinth api.
2. Create a crate modrinth-api that has methods to actually query the modrinth api directly to get back the responses from modrinth-api-types.

Describe alternatives you've considered
I could implement this as a separate 3rd party crate, but I would be reluctant using that in an official modrinth application such as theseus.

Additional context
I split it into 2 crates with the intention of using modrinth-api-types in labrinth as the structs used for returning and having modrinth-api as a separate crate including all the dependencies to trigger HTTP requests.

Not sure if this would be the best way to implement this, alternatively this could be implemented without using it in labrinth itself, but I would still like to have it in the modrinth org.
