[whalemare]

Related to https://github.com/ivanhofer/typesafe-i18n/discussions/656

Allow pass additional parameter to cli named as --project, that allow users to override default '.typesafe-i18n.json' path to config file

Save backward compatibility to allow current users change nothing in it's workflow.

Tested locally with command

typesafe-i18n -p /Users/whalemare/dev/project/some/relative/path/to/config/.typesafe-i18n.json
