Give replicate command a -restore-if-db-not-exists flag

[ipmb]

To get a copy of the database before replication starts, you need to write a shell script like this: https://github.com/benbjohnson/litestream-docker-example/blob/8f4d71055049ccd3cc52f499539e70601bb10d48/scripts/run.sh#L4-L10

Could replicate get a flag like -restore-if-db-not-exists that would restore the database if it doesn't exist prior to starting replication?

This seems like a common use case and it would be nice to be able to cover it with a single command instead of adding an additional script to handle it.

Yeah, that's a good idea @ipmb. I added to the next milestone.

That would be awesome, but just want to note it should imply -if-replica-exists because of first start.
