Different digit-form's for upright/oblique/italic

[pv4]

Is it possible to apply different digit-forms (lining/old-style) to different styles (upright/oblique/italic)?

In iosevka 3.x it was possible by using something like

[buildPlans.iosevka-x]
design = []
upright = ["default-to-lining-figures"]
oblique = ["default-to-lining-figures"]
italic = ["default-to-old-style-figures"]

Moved digit form into variant selector, so now you could set digit form like this:

[buildPlans.iosevka-custom.variants.upright]
digit-form = "lining"

[buildPlans.iosevka-custom.variants.italic]
digit-form = "old-style"

Closing.
