* feat: allow getPreviewLinkData for all links
Only YouTube links were supported in `getPreviewLinkData` previously.
Now, any whitelisted links can have their data retreived using this function, returning the true content type (by examining the header bytes of the content).

* Fix json format
* bump VERSION
* Lint urls.go
