v7.0.0-rc.6

# Version 7.0.0-RC6:

The last release candidate is here. Any future work will be segmented into PRs (whether by @jlucaso1 or I) and then tested heavily, then merged into master and then 7.0.0 will release. I don't have an ETA, but you can use this version now.

Rc6 issues and things to tackle before main release:
- Performance issues resulting from a lot of the LID migration commits and the transaction rewrite
- App State Sync (many errors)
- Up to 30x increase in binary reads (still benchmarking this my discovery is insane)
- History sync
- 1:1 parity with WA Web when it comes to a lot of things to decrease bans


Changes that have been made since rc5:


- increased socket reliability
- Full Meta Coexistence support (pairing with coex, sending messages to someone with it, receiving messages from them, and also being in a group with someone who has it are all handled)
- fetchWAWebVersion works again
- less and less vectors for automation detection, should show reduced bans
- Increased reliability and less crashes
- patched fromMe in some scenarios
- Increased signal reliability as well
