GoEnv: Fast Env Decoder to Go-Struct for Go

What is this?

This package loads environment variables into go-struct with validation built-in. It also tries to load key-value pair from .env file within the root project directory if available.

• Fast implementation without Regexp.

• more options for validation and defaults.
