Add matcher struct to solver matcher package

[bgins]

General Description

Refactor the solver matcher around a matcher struct to make it easier to break matching functionality into separate functions.

Which system(s) or functionality does this affect

This functionality only affects the solver.

Describe the changes, and how this affects/ interacts with each system.

Our solver matcher currently exists as a single GetMatchingDeals function with a couple of helper functions. For each helper function, we need to pass dependencies like the store, tracer, and logger.

We could improve this situation by adding a matcher struct and implement helper functions off it as methods.
