Annotation_scale function - Unit of scale bar : nautical mile

[l-billon]

Hello,

I'm working with R. 4.3.2, and I need to have a scale with the unit nautical mile ( = 1,852 meters), for marine maps. But, this unit is not present in the unit_category ("metric" or "imperial" units).

It would be great if the unit could be added to the list or if someone have any suggestion of adaptation of the annotation_scale function that i could do.

Best,

Lucille
