spanset: enforce the order lazily to gain `fastasc` and `fastdesc` methods

Instead of having the direction of iteration enforced through the ordering of
`start` and `end` attributes of spanset, we encode the iteration direction in
an explicit attribute and always store start < end.  The logic for sort and
reverse has to be updated. The __iter__ is now based on the newly introduced
`fastasc` and `fastdesc` methods.

This will allow other code simplifications in the future.
