upload bundles directly after fetching

[sledro]

• Upload bundles to Celestia directly after the bundle is fetched from RPC or db.
• This is an attempt to reduce Celestia fees by reducing the network congestion caused by hb
• If a bundle fetch fails, the the bundle will attempt to refetch
• If a bundle publish fails, it will retry x times and if it fails every time, the entire bundle will be refetched
