Arbitrary Swaps

[ptrwtts]

Allow orders (seaport only), with arbitrary offers and considerations. Creating them, ingesting external ones, and filling them.

The main goal is giving ourselves complete coverage all orders and transactions, rather than ignoring them. But we could also have some basic functionality that makes them usable:

• Lookup by ID (e.g. get create a deep link to fill a particular order)
• Lookup by private recipient
• Lookup by maker

In the future, could maybe try and detect which users own all of the considerations, and could potentially fill. This could then appear in their "bids received" inbox. Problem is that it's hard to value the bundle, and thus hard to filter spam.
