Issue replacing _parse_blob

I was working on applicationstate.py and I ran into an issue regarding plist parsing. I tried to replace the local _parse_blob function with the standard function from the core, but I ran into errors.
Testing with get_plist_content I tried passing the data to this function, but it failed with this error:
```Error: Type error when parsing plist data: a bytes-like object is required, not '_io.BytesIO'```

I also noticed that this same custom block of code is present in other modules, not just here. I found it in:
- bumble.py
- imoHD_Chat.py
- instagramThreads.py
- safariTabs.py
- uberClient.py
- vipps.py
