Reorganize the existing merge protocol to establish the pre-pending of subtables of ecc ops from each circuit, rather than appending. This is facilitated by classes
UltraEccOpsTableandEccvmOpsTable(implemented in a previous PR) that handle the storage and virtual pre-pending of subtables.The merge protocol proceeds by opening univariate polynomials T_j, T_{j,prev}, and t_j (columns of full table, previous full table, and current subtable respectively) and checking the identity T_j(x) = t_j(x) + x^k * T_{j,prev}(x) at a single challenge point. (Polynomials t_j are explicitly degree checked in main protocol via a relation that checks that they are zero beyond idx k-1).
Note: Missing pieces in the merge are (1) connecting [t] from the main protocol to [t] in the merge and (2) connecting [T] from step i-1 to [T_prev] at step i. These will be handled in follow ons.
