Sequence of expansion samples used in a multi-stage polynomial chaos expansion

Each level entry of the `expansion_samples_sequence` applies to one expansion within a multi-stage expansion. Current multi-stage expansions that support expansion samples sequences include multilevel and multifidelity polynomial chaos.

If adaptive refinement is active, then this sequence specifies the starting point for each level within either an individual or integrated refinement approach.

A corresponding scalar specification is documented at, e.g., expansion_samples
