At the moment you can't recognise the logo with Github's light theme (yes, there are people who use it). With this PR, the logo switches between a light and a dark version, depending on the theme. I hope it is a (small) improvement.
I didn't delete the previous "crowsnest-logo.png" because I don't know, if it is used anywhere else. I have, however, added two new files so that you can easily distinguish between the dark and lightmode logos by their names and so that they are identical in size and cropping.

If this needs to be changed, please let me know.
