Better colour/formatting codes

[cs127]

Neofetch changes:

• The color function distinguishes between 7 and fg properly (7 = white, fg = default foreground colour).
• The strip_sequences function captures ANSI SGR escape codes more accurately.
• The reset variable only resets the text colour and whether the text is bold or not, and doesn't reset anything else.
• Added a workaround for showing bright colour blocks (8-15) in the Linux framebuffer console, by using the blinking text attribute (\e[5m).

Hyfetch changes:

• Changed the Minecraft colour codes so that the dark ones don't reset anything, and the bright ones don't make the text bold.
• Added the remaining Minecraft formatting codes.
• Added extended formatting codes that reset specific things (e.g. colour, bold, italic) instead of everything.
• Changed a bunch of "reset everything" (&r) codes in strings, to only reset the attributes they need to.

I tested everything as much as I could, but I might have missed some stuff. Feel free to let me know if there are any problems!
