Allow setting post dates

[GSI]

Is it already possible to provide a date when publishing through the new command?

I am looking to mass-import existing markdown files, maintaining their original publishing dates.

I found this, which is perfectly acceptable in case wf-cli doesn't provide the functionality.

curl "http://localhost:8080/api/auth/login" \
        -H "Content-Type: application/json" \
        -X POST \
        -d '{ "alias": "user", "pass": "pass" }'

curl "http://localhost:8080/api/posts" \
        -H "Content-Type: application/json" \
        -H "Authorization: Token 05071cb0-6d7b-45e4-5734-68caf081aab1" \
        -X POST \
        -d '{ "created": "2006-01-02T15:04:05Z", "body": "This is a post.", "title": "My Post"  }'
