Allow lockers to resolve deltas on behalf of other lockers

Component

Lock and Call

Describe the suggested feature and problem it solves.

To add more flexibility for lockers and open up new use cases, this idea would be to introduce a new way to pay off deltas by adding the ability for a locker to resolve open deltas on behalf of a different locker.

Describe the desired implementation.

Add a function resolve that nets out two lockers' deltas. Additionally, add the option for a locker to specify a "resolver" address. An initial proof of concept was explored here, along with a hook that could NoOp swaps/modifyPositions to show the Custom Accounting use case.

Describe alternatives.

the balanceDelta's returned by all functions basically become moot with this, correct? Bc accountDeltas could be completely different the the balanceDeltas returned to callers?
