Make `RawConfig` serializeable

[Creative-Difficulty]

I'm serializing RawConfig into TOML in my CLI and for my tests (and also to be able to construct RawConfig programmatically) it is neccesary to serialize RawConfig into a string. Some other issues have been opened about this, so I think the community is interested. This would greatly benefit many projects and I don't think it would require much work for the library. I'm currently considering opening a PR myself.

Also: My (and a lot of peoples) config struct incorporates RawConfig, so not being able to serialize it makes the whole config struct unserializeable.

I'm also curious about how your changes support the following:

Thats another issue, however now i can deserialize it from a string, modify some properties and serialize it back. So at the moment it's just programmatic modification, which really helps with tests.

@bconn98 Sorry for the late response, this is what i found:

@Creative-Difficulty I don't believe either of these are requesting for the RawConfig to be made serializable. However, I'll take a look since it appears to largely be auto generated code
