Support for strict vs common speech modes for Number to Words

[clairernovotny]

Some languages have different ways of representing large numbers, such as en-IN. See #1164 (comment) for details:

I agree that this phenomenon (of expressing everything in terms of lakh, and crore, and not leveraging arab, kharab) is not new - this is in line with my experience, and also a couple of folks I spoke about this (to confirm my assumptions, before I posted my earlier comment) thought so as well.

It's not very different than saying that many (but not all) are familiar with quadrillion (which comes after trillion), but few rarely use it. quintillion etc. are far less known, and very rarely used. That said, the question becomes something like this - in a programming library, should one emit ten thousand trillion, or should the library emit 10 quadrillion. This is ultimately a value judgment and depends on your design principles and use-goals.

If you and @clairernovotny decide to represent everything in terms of crore, I don't think it would be wrong per-se - just a different design choice.

Perhaps what you need here is the ability to switch between strict and common speech modes, each with different outputs.
