My own template repository for cli apps with Go

Some of the code structure and ideas were taken from metafates/go-template.

• use cobra for command line
• integrated viper with cobra to read config options first from cli, then use config files, else use defaults
• separate packages for each stuff for easier modification
• pretty logging with charmbracelet/log
• allow setting logging levels from cli
• allow enabling/disabling colors from cli
• use just for running tasks
