Adapt chat application parsers for the LAVA Thread/Communication/Chat view

LAVA offers the option of displaying parsed chats in a conversation view (comparable to the actual view on the device).

Not all parsers currently make use of this option.

The following parsers are currently compatible:

- LinkedIn
- PotatoChat
- Kleinanzeigen
- SMS
- BeReal
- Burner
- BurnerCache
- Teams
- facebookMessenger

The following parsers require adjustments for the chat view:

- [x] Oops
- [x] ZangiChats
- [ ] bumble
- [x] DiscordChats
- [x] DiscordChatsA
- [x] imoHD_Chat
- [ ] kijijiConversations (This app uses the same structure as Kleinanzeigen)
- [x] kikMessages
- [x] Life360
- [x] Line
- [ ] pingertextfree
- [x] Slack
- [x] telegramMessages
- [x] teleguard
- [x] tikTok
- [x] Viber
- [x] WhatsApp

Artifacts that already use the "__artifacts_v2__" structure are mostly easy to adapt.
