Now uses shared memory, with the added benefit of being faster(~5->~1.1 seconds on my laptop) and not requiring sudo permission.
However, due to Dolphin immediately unlinking the shared memory after its created on Linux, the library now has to run before a game is started while constantly attempting to access the shared memory object. A bug with Python also causes the shared memory to be deleted after the process ends.
The only superficial effects of this update on Linux is that a warning is posted after the library finishes its test and processor usage increases while the library waits to hook onto the memory.
There may be a better way to check for when the shared memory object is created but so far just trying to access the object over and over again seems to be the only thing that has worked for me.
