[Zodomo]

Implemented initial solve Outbox and refactored as necessary in order to adequately test it.

issue: #2377

Comprehensive testing of the Outbox is not yet finished as of this comment. I just wanted to push what I had so @kevinhalliday and I could sync and pivot if necessary.

Do we know why bindings all changed?

Actually maybe just need to regen. Looks like that check failed

Feel free to add tests in additional PRs. In general let's try to keep PRs a bit smaller than we have done at this point

I just tried reverting the changes to the allocs/bindings/golden files via rebase and pushed, however the action failed. When regenerating all of it, new versions are still produced. Not sure why it would fail when freshly regenerating everything.
