For the byte view tab, a large part of the problem is, I think, that it has to
be completely filled with hex dump text, and, with a lot of bytes to dump, that
can take a while.

This calls for a "lazy hex dump" widget, where you just associate the widget
with a data source and have it format only the stuff that's visible, similar to
the widget we're using for the packet list; unfortunately, GTK+ has no such
widget, so, unless there's a third-party widget for that, we'd have to roll our
own.

We might be able to do something similar for the packet detail pane, but that
still means constructing the protocol tree, so there's not as much work that
could potentially be saved by laziness on the part of GUI widgets.
