Consider using spf13/viper for config management?

[DaniruKun]

For the configuration management that is done in https://github.com/evolution-gaming/ease/blob/main/config.go , you can also try out https://github.com/spf13/viper
It's a very mature and standard library for Go configuration management that supports 12 factor app basics, and does most of the stuff for you (automatic env var loading, various format deserializers, multiple config path search etc.).

Thanks @DaniruKun ! This is a viable option, especially if at some point will adopt cobra for CLI as per #11.
