[FEAT] Functionality to filter blocks

[dillongardner]

Is your proposal related to a problem?

For larger scale ER problems, it is common to run into large blocks that dominate the compute time. In some cases, a few blocks can be so large as to make the entire blocking strategy infeasible.

Describe the solution you'd like

Provide a mechanism for evaluating an removing specific blocks if they meet certain criteria. At a minimum, this should allow for removing blocks of a certain size. But ideally, provides enough flexibility to allow users to right customer filter logic.
