Readme logo for dark-theme users

[asger-finding]

Is your feature request related to a problem? Please describe. The vercel/hyper readme uses a logo with text targeted towards light theme users (the Hyper text is in black) which makes readability harder, and uglier, for dark theme users like myself.

Describe the solution you'd like Use two image assets in this repository and append #gh-light-mode-only and #gh-dark-mode-only to their srcs respectively. This allows for GitHub to only show the image targeted towards the user preference. Example: asger-finding/anotherkrunkerclient
