The existing Quail ITRANS scheme is incomplete and not applicable to the
language - does not support some common characters and does not handle
its quirks like 'chillu's.  Also, the Inscript method has errors and is
not updated to the latest standard.

This patch implements the basic sufficient features of the Mozhi
scheme (the complete scheme is unnecessarily complicated IMO) and
updates Inscript.  Refer:

Note: If checking on Ubuntu (and maybe Debian) set the font to Noto
Sans Mono to avoid the problems with the default one.
