Did some initial research on libraries that could help us.

libenvpp can parse, validate and cast env variables, but not directly read from a .env file. Is actively maintained
cpp-dotenv can read .env files, but does not validate or cast them. Not maintained.
cpp-validator general purpose validation library. Does not cast.
reflect-cpp general purpose serialization, deserialization and validation of json, yml and more. Does not support ENV format, but could be handy if we ever want to handle those types of files.

As it stands, I think libenvpp is a good fit for our needs. If we really want to use a .env file from disk, we could read it into the env, and then use libenvpp. Or we choose not to do the file reading and force the users to source .env && game for example.
