Feature: The horizontal mouse wheel scrolling in the process list

htop with the process command line column enabled provides very wide and very useful text output that currently requires keyboard controls to patiently scroll.

It is convenient that long non-wrapped and tabular lines in programs like less and nvim can be scrolled horizontally via the respective mouse wheel (less also supports scrolling via the mouse drag events, maybe for a separate Issue).

As in the title, this is a feature request for the horizontal scroll wheel scrolling support in the process list.

Via the mouse / pointer device buttons that xev identifies as button6 and button7 and wev identifies as axis: 1 (horizontal).
