Add Wolfram language support

[rcon56]

The ascii image mainly consists of 'W' and 'O' because the logo of Wolfram Language is a WOLF and wolves howl like 'woooooooooo' I guess 👀.

Here is the screenshot in dark background with true color.

Great logo! I'm a bit concerned about how this would look in light terminals (see #33 (comment) and below comments for recent conversation). But I suppose the wolf would just become negative space on a light terminal, which is OK. But if you can think of a reasonable alternative to the white color, that would be appreciated. 🐺
You also might want to experiment with filling in the outline with black text, so that the wolf would still have a black outline on light terminals.

(Overall I think we'll need to replace white with None colors in logos to use the terminal's default text color)

Thanks for your suggestion! I have tried what you mentioned above in terminal with different themes and found that:

• Using default text color for the main body of 🐺 might be the best solution for now. (AFAIK, the feature of None color has not been merged into the main branch or I just overlooked?)
• Using grey can be acceptable in most situations.
• However, I think adding black text to represent the border will break the integrity of the ascii image because it's hard to portray such a thin borderline by ascii characters.

That's right, that was more of a note-to-self I guess. I should probably get started on that 🙂

That sounds good for TrueColor, but I don't think it's possible with the 8 standard colors.

I see what you mean.

I just had an idea for a relatively painless way to implement None colors, so I think I'll hold off on this PR for a bit and see if I can get that sorted out.

#625 has been merged, so please merge it into your branch and check out the logo 😃

Great! I have merged it and also changed the white color to the grey one in the true color scheme.

Here's what I got in light terminal :)

Looks great! Thanks for your patience!

@spenserblack Maybe we should also map Rgb(255, 255, 255) to Default?

I was thinking about that in #625, but here's why I hesitated:

• True color IMO should be the "real" color of the logo. If the user wants control over that (light theming, changing contrast), they can use --true-color never.
• True color is where contributors get to express more artistic freedom, like creating gradients. I could anticipate a gradient with a #FFFFFF start or end, which would be interfered with by a Default remapping. That's just an example, but I'm concerned about interfering with a contributor's intent when true color kind of promises that they can do whatever they want.
• If we remap #FFFFFF (255, 255, 255), that opens the door to requests to remap #FEFFFF and down. Possibly any color brighter than #CCCCCC (roughly 75% brightness) would be on the table.

TBH I think a note in either the README of Wiki stating something like

If you use a light terminal theme, struggle with high contrast colors, or for any other reason need to limit onefetch to the 8 ANSI colors, you can use onefetch --true-color never. For regular usage you can add this to your .bashrc: alias onefetch='onefetch --true-color never'

would be enough.

tl;dr I've been thinking of the basic colors as "compatibility mode" and true colors as "pretty mode".
