System messages are not parsed correctly.

hi, The system messages in the export I added are not parsed correctly. I think WhatsApp changed the format. fyi

WhatsApp Chat - Test.zip

Historically system messages did not have an author, but now it seems like new exports follow some new rules:

• In a 1 to 1 chat, the system messages are labeled with the name of the person you're texting.
• In a group chat, it's a mess. Some of the messages are labeled with the group name, but others use the name of the person that does the action? Here are some examples:

[14.08.2024, 21:00:10] My Group Name: ‎Messages and calls are end-to-end encrypted. No one outside of this chat, not even WhatsApp, can read or listen to them.
[14.08.2024, 21:00:10] Boris: Boris created group “My Group Name”
[14.08.2024, 21:00:11] My Group Name: ‎Boris added you
[14.08.2024, 21:01:57] My Group Name: ‎You're now an admin
[14.08.2024, 21:00:12] Boris: Boris changed this group's icon

I guess Whatsapp considers some of these actions as "done by X person" so I think it's fine if we don't consider them as system messages either

I'm not 100% sure my assumptions are correct, this will need some more testing
