Parsing unit pairs, eg. 8lbs 6oz or 6'4"

[nathan-muir]

In the source, there's a comment about parsing USA/Imperial style values, like 8lbs 6oz or 6'4"

However, if we try new Qty('6\' 6"'), it fails with the errorQtyError {name: "QtyError", message: "Unit not recognized"}

So, is this a bug? or, a intended feature of js-quantities? Or, just an old/ outdated comment?

I hoped to use this library for this feature as well, since they are mentioned in the comments, but it doesn't appear to be supported in the specs as well.

Can we get an update from the maintainers? Is this meant to be supported?
