Share intent: Being able to send more than 1 bookmark at a time

### Describe the feature you'd like to request

Chrome has a feature where you can select all tabs and share. When shared to floccus it treats it as one very long URL with no title.

### Describe the solution you'd like

Haven't tried with FF or other browsers, but it would be nice if there was some way(s) to get more than 1 at a time, as most major browsers don't allow exporting bookmarks en mass on mobile from which an import would be easy

### Describe alternatives you've considered

Can export on the desktop to a cloud drive and import from there. There are existing workarounds, hence feature request as it's not a bug.
