dashlanePassword filter

dashlanePassword returns structured data from Dashlane using the Dashlane CLI (dcli). filter is passed to dcli password --output json, and the output from dcli password is parsed as JSON.

The output from dcli password cached so calling dashlanePassword multiple times with the same filter will only invoke dcli password once.

!!! example

```
{{ (index (dashlanePassword "filter") 0).password }}
```
