Fix enumeration of GlobbalPlatformISDR during card_init()
We used __subclasses__(), but this only returns the immediate subclasses and not all further/nested subclasses. Instead, we must use the pySim.utils.all_subclasses() function to really get all of them.
The hack to use the method signature of the constructor to determine if it's an intermediate class didn't work, as even GlobbalPlatformISDR has a optional argument for non-default AIDs. So let's introduce an explicit class attribute for that purpose.
