Separate files for Iosevka Extended

Is your feature request related to a problem? Please describe. Iosevka is my favorite monospaced font, but the Extended variants of the font are the only ones i enjoy using, and some programs just don't let you specify font variants like this, and in some programs that do, it's somewhat of a hassle.

Describe the solution you'd like I'd like for there to be builds of the font that contain only the Extended glyphs.

Describe alternatives you've considered Using a different font, using a different application.
