Stage 2 of the VPE commit - this adds some general routines for VPE circuit generation given a preparation circuit and a circuit to do time evolution. I've also made some minor changes to the estimator files (as there was some duplicate code, and also the estimator wasn't stable under the current choice of times).
@ncrubin , @Wuggins , can you perhaps check this out?
