feature request: filter for offline validators

[JustinDrake]

Thank you for all the great work on beaconcha.in—I use the tool daily! Adding an "Offline" row in the beaconcha.in/validators selection menu (see screenshot below) would be super helpful :) Filtering for offline validators would allow to sort offline validators, e.g. by activation timestamp.

@JustinDrake good idea, added to our backlog <3

Thank you for adding a tab for offline validators!

Would it be possible to have offline validators sortable by last attestation? :)
