Remove deprecated mb as symbol for millibar unit

twmr · twmr · commit 3d0afe0e90ca · 2022-04-20T00:12:10.000+02:00
In order to be consistent with the other pressure units that are derived
from the unit bar, we should use mbar as the symbol for millibar. The
symbol mb, which is a deprecated symbol, because the b in mb conflicts
with the metric unit barn, was removed. Since the other bar units also
define an alias with a written out SI prefix, this change also adds the
unit "millibars" as an alias for mbar.
