CLI export to .1pux

While the command-line 1Password client works quite well in day to day use, one feature that it does not support is exporting a backup file in the 1PUX format. 

The only way we can do this now is to run op item get $id for each item in op item list, but this does not create as solid an export as using the 1PUX format.

I've searched and could not find threads on this, nor a space to submit feature requests. So I'm posting here, hoping somebody will pick this up and add it to the appropriate list somewhere.
