Add Madhuban about fonts

[emmamarichal]

Hi @jaikishanpatel! Thank you for your submission :)

I quickly reviewed the font, there are a lot of issues regarding the variable export, but we can fix them on our side, if the project is accepted.

I put here the fontbakery report:

🔥 FAIL: Checking OS/2 fsType does not impose restrictions. (com.google.fonts/check/fstype)

• 🔥 FAIL In this font fsType is set to 8 meaning that:

• 🔥 FAIL Font is missing the 'gasp' table. Try exporting the font with autohinting enabled.
  If you are dealing with an unhinted font, it can be fixed by running the fonts through the command 'gftools fix-nonhinting'
