Basic support for Hebrew characters

[ebkalderon]

It would be amazing if Fira Code supported basic Hebrew characters and diacritics. Thankfully, there aren't very many code points in the Hebrew language Unicode block, and individual letters are detached from one another akin to Latin or Greek, so hopefully it shouldn't be too tricky to implement in Fira Code, when compared to more complex writing systems that exist out there.

While I'm unfortunately not a font designer myself, I would be more than happy to review the output for correctness and legibility, if you or anyone working on this needs a second pair of eyes.

Thank you for this delightful font! It's served tons of people very well over the years. ❤

For the sake of inspiration, perhaps it might be useful to look to an existing sans-serif (albeit variable width) Hebrew font to learn from example. Noto Sans Hebrew seems like a pretty decent example of such a font, IMO.
