Add options for link preview when sending messages

Feature Request

Signal-cli is offering the command parameters for link preview via --preview-url, --preview-title, --preview-description, --preview-image. It would be awesome to to add these to the json params of the send v2 endpoint. This would allow a greater message formatting which can be great for e.g. sending web scraping findings.

As much as this would be handy, there could be a potential vuln here given this debated signal issue https://www.bleepingcomputer.com/news/security/signal-says-there-is-no-evidence-rumored-zero-day-bug-is-real/

Thank you for quick response. As far as I can see its just rumors. The Signal team has been notified and was unable to find any evidence to support the claims. In this regard, I have complete confidence in the Signal team's highly responsible management of their app's security—after all, it is the foundation of their messaging service. For people still being concerned the best way is to disable the feature in the settings.

Having the feature available for people having full trust in signal would be still very amazing :). I would submit a MR but I am not familiar with Go.
