Add InconsolataLGC font

[iloginow]

Description

Adds InconsolataLGC (Latin, Greek, Cyrillic) font.

Inconsolata is one of the most suitable fonts for programmers created by Raph
Levien. Since the original Inconsolata does not contain Cyrillic alphabet,
it was slightly inconvenient for not a few programmers from Russia.

Inconsolata LGC is a modified version of Inconsolata with added the Cyrillic
alphabet which directly descends from Inconsolata Hellenic supporting modern
Greek.

Regarding the 'left arrow' issue: I tested some more fonts and none of them got this ugly 'left arrow' gap. So conclusion by exclusion: the problem is somehow the InconsolataGo font itself.

Hey thanks for the new PR. I am guessing it is due to my comment here #197 (comment) ?

Thanks for testing more fonts and narrowing it down to the InconsolataGo itself. This is very helpful! Really appreciate it 😄

That's strange, hopefully we can get to a solution.

I have been a bit delayed lately but I will get your PR and others merged in somewhat soon.

Thanks for the patience
