Add Espresso Mono

[properly-strawberry]

Added Espresso Mono font extracted from Espresso.app and converted from Mac .dfont format. The font is a derivative of DejaVu Sans Mono, goes under same license.

It's very subtly different from DejaVu. While the license allows us using it, I'm still going to reach out to them to see if they mind. There is also no obvious way for users to obtain the font, other than via your conversion on GitHub. I.e. the website link doesn't take them to the font (although on a Mac I guess you can extract it from the app's trial version...). I kind of prefer people being able to go to the source if at all possible.

That is understandable. Feel free to close the MR if you feel like adding it doesn't outweigh the ambiguity.

Sent them a mail, let's see what they say :) I'd be surprised if it's much a problem, it's not like the font itself is a major marketing asset for them and inclusion here might add some visibility to their product. But this is a creators-first project and I don't want to presume.

By the way, I just dropped a big update, so you might want to rebase. Also, a script has been added that you can call to add some font metadata to the json:

python3 info.py --name espresso-mono

It requires the fonttools and hyperglot libs, but since you're into this stuff you might already be familiar with those :)

Not too familiar, but I like getting to know new things 😁

Speaking of download links: https://github.com/properly-strawberry/espresso-mono I uploaded all the files, original and intermediate, so there is a download link (technically). I could add a link to their app, that would be something.
