Upgrade, Remove DYE, Fix up failing tests

See merge request aptivate/internewshid!54

It seems like the test only cared if things were converted
to the correct datetime and not the exact values with all that
microseconds malarky.

There are 40+ warnings and they're not really breaking
anything JUST now, so I'd rather just get moving on with
fixing the really breaking things. Once we get a little
further in the upgrade, these will break too ...

Also shorten those marker notes.

I assume the transport code can just be replaced with
a different import statement. The `hid` module code looks
like it needs a special loading. I think I've captured this
in this change.
