[ Lavi ] weak spacing before 'colon'

[Deevad]

The spacing before the colon in the font Lavi is a bit weak.
The consequences: many time a empty space was added before the colon to workaround this issue. This is not correct. The problem is revelant in this discution ( Deevad/peppercarrot_ep14_translation#3 (comment) )

( Note: semi-colon, and other punctuation symbols might be affected )
