Consider improving penpot-export CLI

[roberto-red]

Description

penpot-export has a single CLI command with no options, penpot-export.

It always requires a user configuration file to work.

Expected output

Consider adding a parameter to provide an alternative user configuration file. E.g. penpot-export -c ../my-other-project/penpot-export.config

Consider improving the user experience by providing a way to execute simple cases with only commands and no configuration file. E.g. penpot-export -h https://my-instance.penpot/ -t $AUTH_TOKEN typographies -f $PENPOT_FILE_UUID -o src/styles/typographies.css
