Missing initial and medial forms of U+066E, U+066F, and U+06BA

[dscorbett]

U+066E ARABIC LETTER DOTLESS BEH, U+066F ARABIC LETTER DOTLESS QAF, and U+06BA ARABIC LETTER NOON GHUNNA are dual-joining, but in this font, they are missing their initial and medial forms. The following image shows them in initial and medial contexts with U+0640 ARABIC TATWEEL.

Thanks for this issue. Those forms added to Vazir 27.0.0.
