BTW: this also includes commits from #234 so that should be merged first, then I'll rebase this. |

This PR addresses some feedback on #233, in particular to move the decoding out of regular mapping decoding.
This new PR's approach has all the range mapping decoding done after regular mapping decoding. Initially all mappings have a
[[IsRangeMapping]]of false. If there are range mappings encoded, then the next decode step will update the field to true for any range mappings.If a range mapping is specified for a mapping that doesn't map an original location, or the offset is out of range, then an error is optionally thrown.
One semantics question: should it also optionally throw if the mapping has a [[Name]] too?
