Hello,

I have an error when trying to donwload sheets, i took this one as an example but its the same with other ones.

Brahms Lullaby in medium difficulty : https://cdn.flowkey.com/sheets/vSWc6EqSsS2fYqsWE/300/0.png

Here is the CMD output when trying to load it :

Cheers, your program is usually awesome when its working =)

This will be fixed by this PR - https://github.com/MatthiasLienhard/flowkey_dl/pull/36. Since a different error message "Not Found" is returned when the next image in the series is not found, the while loop didn't break and the code proceeded to this line patch = imageio.imread(r.content, format='png', pilmode="RGBA") thus causing the error you've seen.
