The goal is
I have some lower-cased environment variables that I can not change them because they have been used for many applications and also I want to use envconfig library which is so simple and useful I think.
This PR is so useful for me maybe also for the whole community.
Usage
It works only when you pass a struct tag upper as false. Otherwise there no thing to change on current usage. When we pass upper as false, envconfig stops the looking for upper-cased environment variables.
