Parse env vars after loading config from sources #282

Closed dworthen closed 3 weeks ago

Parse environment variables into config after loading values from all sources.
Uses string Template syntax of ${SOME_VAR} to reference environment variables.
Support $${} syntax for escaping ${} in string templates. Allows for the $${timestamp} use case so users may perform their own string parsing after config loading.
load dotenv files from env sources, preferring values defined in earlier files over later ones and preferring values defined in dotenv files over os.environ.
