Consider what it would look like to allow tools to provide types to the config

[orta]

Somehow the runtime/compilation aspect will need to expose the set of library targets to the eval phase

#if canImport(PackageConfig)
import PackageConfig
import Danger

// Generic
let config = PackageConfig([
    "linter": ["rules": ["allowSomething"]]
])

// Extension provided by Danger
config.danger = [
   .disabled(true)
]
#endif

The settings will need to be coerced though the JSON and back somehow, but maybe codable can do that?
