aes key error on launch

[karlo2105]

Hello @beardypig

With streamlink portable latest build, message below is displayed when it is started with aes key.
Is there any chance for workaround ?

Exception in thread Thread-1:

You got an example URL so I can reproduce?

Take a look at E-Mail. ;)

I suspect it's because you are passing a string as the AES and you will need to pass bytes for Python3. eg. b"\xf3\x12\x32...", should be a simple fix.
