Freezing Rain & Drizzle missing

[BorisAnthony]

These are by far the nicest weather icons out there. Subtle, simple, clear. Thank you for making them available!

However, they are not complete sadly.
While the set does include a few "codes" that are incredibly specific ( e.g.: most of the precipitation + thunder combos ), and some that are not present in the simplified WMO set (this is a separate peculiarity), in the overlap (between WMO and NRKNO/YRNO), we are missing "Drizzle" and "Freezing Rain" variations.

I know NRKNO/YR.NO do not seem to report drizzle or freezing rain (or freezing drizzle), but
(Also it seems that drizzle used to be supported, but at some point it was dropped. See the old code here: https://github.com/metno/weather_symbol/blob/master/src/Code.h )

I can appreciate the difficulty in differentiating these, visually, in the iconographic language adopted for this wonderful set, but I don't think it is impossible. I made an attempt, which I've attached. (This is done in Figma and I'd be happy to share the SVGs if someone wants to engage on this.)

If anyone's interested, here is my (messy) YR.NO <-> WMO codes matching matrix:

Is there a possibility to discuss adding these?
