Motivation:
When initializing an `HTTPMethod` with a `String` we currently switch over all expected values to pick an explicit value, only to overwrite our found explicit value with a catchall `RAW(value: String)`. This doesn’t make a ton of sense. This went unnoticed because we use the conditional conformance on `RawRepresentable` to be `Equatable`. But `switch`es don’t use the `Equatable` protocol to match enums. The issue is visible there.
Modifications:
Added a testcase with a switch that fails, if the `.RAW(value: String)` value is used for `”GET”`. Removed the final overwrite in HTTPMethod(rawValue: String). Therefore the test passes.
Result:
We can initialize the HTTPMethod with a String and get an explicit value.
Motivation:

Modifications:
* Add `init(rawValue:)`
* Add `rawValue`
* Add tests in HTTPTypesTest.swift
Result:
Users no longer have to write their own conversion methods.
