Allow for translation into a hardware-native gate set during creation of subexperiments

[caleb-johnson]

If our cutting decompositions were specified in terms of Eagle/Heron basis gates, it would give users the opportunity to transpile one circuit and then run all the subexperiments without having to transpile so many circuits

[caleb-johnson]

It would be nice to leave our QPDBasis decomps specified as-is, as they tend to follow the literature more directly.

We may allow users to specify a basis gate set for which to specify decompositions. The default can be the eagle/heron basis set. When ckt generates experiments, it will translate the QPDBasis decomps into the specified basis set before adding them to the subexperiment circuit

[caleb-johnson]

The equivalence library in Qiskit may give us a nice interface through which we can translate our gates before applying them to the circuit in generate_cutting_experiments, partition_problem, etc.

generate_cutting_experiments, partition_problem, etc. may take an optional basis gate set as input
