[Character Request] Pitman duodecimal digits

[throwaway571]

I'd like to request U+218A ↊ and U+218B ↋. These were proposed by Isaac Pitman for the digits ten and eleven in base 12, and are currently actively used by the two Dozenal Societies.

Iosevka is currently feature locked for 3.0. Mark as post-3.0.

Done

@be5invis Is U+218B affected by cv46?

[be5invis]

@throwaway571 No. I know there are some alternative notations of these so I disabled variants on purpose.
Another interesting thing is that do they have old-style form?

[throwaway571]

@be5invis I haven’t come across an old-style form yet, but that may be by design. In the issues of the Duodecimal Bulletin prior to July 11↋↋ (decimal 2015), old-style numerals were used contrastively to represent decimal numbers, but I’m not sure what the current policy is. Let me confirm with the current editor and I’ll get back to you.

In any case, the flat bottomed eleven is definitely attested.

[be5invis]

@throwaway571 OK I will add that back so cv46 can influence both 3 and ↋.
