Python script to migrate watched status and watched progress between servers

[Ozymandyaz]

Hi @Ozymandyaz, Thanks for updating the original script. I really like that i can filter which user I want to sync. I keep getting a json.decoder.JSONDecodeError when i run the code. I also got the same error with the original Emby2Jelly python file, but with that one, i got far enough to be able to create the initial --tofile. It was the --fromfile that produced the error. I also tried without any file and it also failed. I double checked the jellysync.ini file and it looks correct. I tried both local IP and reverse proxy URL. Same error. Full error below.

Traceback (most recent call last):
  File "C:\Users\Essjay\Documents\Emby2Jelly\jellysync.py", line 535, in <module>
    source(selectedUsers)

Let me know if you know what might be causing this.

Its entirely possible that From File is buggy, I did not test it much as I've always transfer between live servers. I'll take a look when I have some time.
