Requiring the states to be a zero-based and contiguous makes it harder for some pieces to support different sets of different states based on what they contain. For example, an ImportPiece only supports states for splitting the names inside a single combinator when there is more than one combinator. To model that with contiguous states requires the piece to carefully track how state indexes are shifted or splitting pieces into different classes to handle the different sets of states. Instead, with this change, we simply allow the piece to return a list of states that may be non-contiguous. They can then omit states that don't make sense given the piece's contents. This makes ImportPiece simpler and I think will be useful for other pieces that have a variety of ways they can split. Also wrap state values in a class to make things a little clearer and more type safe.

This required tweaking the way partial solutions are ordered so that the solver doesn't avoid overflowing solutions that will ultimately lead to non-overflowing lower cost ones.
