rbwFields name [arg...]
rbw returns structured data retrieved from Bitwarden using
rbw. name is passed to rbw get --raw, along with any extra args,
the output is parsed as JSON, and the elements of fields are returned as
a dict indexed by each field's name.
The output from rbw get --raw is cached so calling rbwFields multiple times with
the same arguments will only invoke rbwFields once.
Example
{{ (rbwFields "item").name.value }}
{{ (rbwFields "item" "--folder" "my-folder").name.value }}
