Update units for current SI prefixes

Following Resolution 3 of the 27th General Conference on Weights
and Measures (CGPM) in 2022 [0], update oslo units to include
'ronna' and 'quetta' for decimal prefixes.  Although ISO/IEC
80000-13 has not yet been updated for the binary equivalents,
it's safe to assume ISO will follow current practice [1], so
those are added as well.
