fix!(cli): Fix edid config loading from file, envs

BREAKING CHANGE: edid no longer provides --config for selecting the path of the configuration file to load; edid.toml (if present) and EDID_* environment variables are loaded with the latter taking precedence if settings are defined in both locations.

If edihkal_url is not specified from either config provider, a default value is used: "http://localhost:8080"

build(cli): Add figment for config from env & toml

build(cli): Remove config dependency from edid

Closes #32 (closed)
