Hindi letters should reverse and join in some cases

[talbenmoshe]

Hi,
There are some Hindi letters that when combined, they need to appear reversed.
For example, this "नि" is made out of 2 letters: न and ि. When combined they appear to be reversed and joined.
But they are not rendered correctly in opentypejs.

Here's an example used in https://opentype.js.org/index.html:

(Using poppins font which supports Hindi)

fontforge doesn't render it correctly, so I wasn't able to quickly find out which OpenType feature is used to achieve this, but this library doesn't support that feature as of yet.

@Connum I am facing the same issue, earlier I was using pdfmake js which uses pdfKit and fontKit.
I found a similar issue with fontKit

Not sure if this could help someone in fixing this issue.
