[BUG] memuc_run calls hang

[Romhast]

When I use the codes below, randomize never gives any output, it seems like it goes into an endless wait. and I noticed that it does this when you use it after the stop_vm command.

from pymemuc import PyMemuc

memuc = PyMemuc(debug=True)

memuc.stop_vm(vm_index=0)
memuc.randomize_vm(vm_index=0)
memuc.start_vm(vm_index=0)

Occasionally memuc.exe will hang on a command. pymemuc tries to avoid this by using timeouts on the exec calls but those aren't very reliable.

Often times I found that when commands like this hang, having the 'MEmu Multiple-Instance Manager' window open while applying commands prevents a hang.

Best practice is to have a thread which executes pymemuc commands that isn't joined by the main thread of your program, assuming you don't need the output of pymemuc read.
