Background color config

[DyckGerman]

Really happy about the introduced font color option.

It looks like my zsh theme (or something else) makes the background gray, but i want black.
Could you please add background color option and use it to clear screen before frame rendering?

matrix-rain/ansi.js

Line 4 in fa85e94

clearScreen: () => `${ctlEsc}2J`,

Can you confirm you are on 2.0.3? I added this https://github.com/nojvek/matrix-rain/blob/master/index.js#L199 which should force a black background.

you can npm install -g matrix-rain again and it should pull the latest version.

I checked that again and it is reproducible with 2.0.3 on Debian 9 and Ubuntu 18

According to colors section from here, 40 as a black background should work, but for me only \x1b[30;1m worked as a real black.

Just don't mind, i believe it can be treated as an environment issue and closed

30;1m is the foreground color, may be I'll do both and clear the screen.

@DyckGerman can you try re-installing with npm install -g matrix-rain to use 2.0.4, I'm doing a clear with both 30 and 40 (fg and bg).

@nojvek, tried 2.0.5 on Ubuntu again, see no improvements. I will share the code that works for me
