Expression for decomposition of various values into smaller limbs or microlimbs.

This relation enforces three types of subrelations: 1) A subrelation decomposing a value from the transcript (for example, z1) into 68-bit limbs. These relations will have the structure lagrange_even_in_minicircuit⋅(a - a_low - a_high⋅2⁶⁸) 2) A subrelation decomposing a value of one of the limbs used in bigfield computation (for example, the lower wide relation limb) into 14-bit limbs. These relations will have the structure lagrange_even_in_minicircuit⋅(a - a_0 - a_1⋅2¹⁴ - ....) 3) A subrelation making a microlimb range constraint more constraining. For example, we want to constrain some values to 12 bits instead of 14. So we add a constraint lagrange_even_in_minicircuit⋅(a_highest⋅4 - a_tail). In a separate relation both a_highest and a_tail are constrained to be 14 bits, but this relation changes the constraint on a_highest to be 12 bits.

Parameters

evals	transformed to evals + C(in(X)...)*scaling_factor
in	an std::array containing the fully extended Univariate edges.
parameters	contains beta, gamma, and public_input_delta, ....
scaling_factor	optional term to scale the evaluation before adding to evals.
