Monitor bandwidth usage.

#LABEL=<span font='FontAwesome'> </span>
#IFACE=[automatically determined]
#DT=3
#UNIT=Mb
# Exposed variables: rx, wx, tx, unit, iface
#PRINTF_COMMAND=printf "${LABEL}%-5.1f/%5.1f %s/s\n", rx, wx, unit;
Note that the interface will be guessed using ip route but it can also be specified
using the $IFACE property.
On the fly interface switching is not supported, if you change
your default interface, simply issue i3-msg restart and the script will pick
up on the new default. However, the block will wait until a default interface
is found upon starting, so no restart is needed if you start i3 and then connect
to wifi later.
