Feature request: select account in `op://` url querystring

Hi there!

Had a feature request I'd like to make.

I have several environment variables with 1Password secret paths across a couple of accounts, some of which are in my environment only when my working directory is inside some subpath. The env vars specified in my rc files tend to be with a personal account while some of my work ones are when I'm in a work-related directory. The problem with this is that when I run `op run` (with or without an explicit `--account` specified), it fails because the paths span multiple accounts.

Would be great to be able to specify the account as part of the url. Something like the following:

`op://path/to/secret?account=personal`

Thanks!
