📝 Summary

  • Current behavior of bundles is that:

    1. All transactions in a bundle must be included in specified order, with no transaction inserted between them, OR
    2. If any transaction reverts, then no transaction from the bundle will be included EXCEPT
    3. When user specifies reverting transaction hashes in their request, the builder can still include the bundle with one or more of the transactions failing within it
  • This PR makes it so when users specify reverting transaction hashes in their request, the builder discards the transaction(s) on error

Deferring decision on the conventions to @dvush and @avalonche since they frequent this codebase more than I do

re: styling - I think breaking lines looks better but no strong opinion this or that way
