Support 1pass

[yardnsm]

One limitation of the 1Password CLI is that it is DAMN SLOW, as it requires an internet connection to fetch data from your vaults. Also, it uses tokens that expire after 30 minutes.

There is another project called 1pass, which is (according to the README) a caching wrapper for the 1Password CLI.

It would be nice to add support for this wrapper, as it would improve the experience of this plugin, while preserving the support for the official op CLI.

We could have an adapter for each CLI, and the user can configure which adapter to use.
