Icon Request: HD icon

I thought it would be nice to have a HD icon, like x-square and many others.
I did really on Illustrator something like this:
 (ignore the black `D`, I don't know how to make it intersect)

Inspired by this:
https://material.io/tools/icons/?search=hd&icon=hd&style=outline

* Icon name: HD (High Definition)
* Use case: Video player
* Screenshots of similar icons:

I think if you can get the margins correctly, it can become a really nice icon and not hard to make.

This is the project, in case anyone wants to play with it:
[x-square-hd.ai.zip](https://github.com/feathericons/feather/files/2950638/x-square-hd.ai.zip)

Review the existing icon set and contribution conventions before working from the supplied Illustrator archive and the linked Material Design reference. Compare the proposed HD mark with neighboring icons for margins, stroke treatment, and naming; done means a consistent HD icon is added to the set and the project’s checks pass.
