Split the logic for loading a value from parsing the value, that way we only need to check if the env var is required in one place.
Prius helps us ensure that our application always boots with the required state. However in large applications with multiple contributors, this can cause a configuration error in an unrelated component to break the entire application. Providing a default value allows contributors to safely introduce new configuration without worrying if the application breaks. For example: ```ruby Prius.get(:my_worker_pool, type: int, required: false, default: 0) ``` It also means that boolean flags that are optional can be made to have a default value of `false` rather than `nil`. Note: This change _does not_ allow you to specify a default value for required config, for obvious reasons.
