Add option to specify output width

[boldandbrad]

Is your feature request related to a problem? Please describe.

I use https://github.com/anuraghazra/github-readme-stats in my profile readme as well. I like using this in conjunction with streak-stats, but they output different widths. While readme-stats does support a width option, streak-stats does not.

Describe the solution you'd like

A width option that specifies the output width of the info graphic in pixels (similar to readme-stats).

Describe alternatives you've considered

Use the readme-stats width option to match streak-stats, but this is not ideal if I’d like them both to be smaller.

Shrinking the width is not recommended since there won't be much padding around the text, but I can implement this option without much trouble
