feat:reliable channels improvements

[fryorcraken]

Description

List of improvements to do for reliable channels:

• Offer local storage option for SDS message:

  js-waku/packages/sds/src/message_channel/message_channel.ts

  Line 93 in 115cdd2

  localHistory: ILocalHistory = new MemLocalHistory()

  , include loading strategy (re-emit all messages at start?)
• fix missing unsubscribes:

  js-waku/packages/sdk/src/reliable_channel/reliable_channel.ts

  Line 495 in 115cdd2

  // TODO unsubscribe

• React hooks
• Review how "missing message" events can be used. Maybe add a "sync" event status, to let dev know whether:
  • No missing messages "all synced"
  • Some missing messages, and maybe a number "N messages to sync"
  • Some missing messages, but gave up trying "N irretrievable messages"
  • or just ensure that missing mesasge/irretrievable messages event work, and show how to use them
• Ensure no dupe events for missing messages, or in any array
• Ensures that it works, even if previous messages were marked as irretrievable
