Setting environment variables for Starkli

For the majority of flags available on Starkli you can set environment variables to make the commands shorter and easier to manage.

Setting environment variables for Starkli significantly simplifies command execution and management, thereby enhancing efficiency, readability, and control when using Starkli.
