This is only the framework for a new protocol handler that should simplify
adding, extending and debugging the actual protocol messages.
The summary is:
- each protocol interaction is a subclass of Msg() that handles the data sent
and received from the device.
- the list of messages for each device is stored in a dictionary the caller
initializes by providing the protocol version
- those messages are addressable via the Interactions enum through the
Protocol class
- the messages can be run via execute(), taking and setting the obvious
properties on the object
- actual communication is done via a single callback that takes/returns a
NordicData object for the request/reply.
So after the basic setup, the caller can do this:
p = Protocol(ProtocolVersion.INTUOS_PRO)
name = p.execute(Interactions.GET_NAME).name
p.execute(Interactions.SET_TIME, time.time())
This completely separates the protocol from the implementation where we want
the result of that exchange, ideally paving the way for better testing and
easier debugging of what's happening on the wire. Well, ether.

This function doesn't process the data beyond the logging required. It simply
sends the request and returns the reply, whatever that is.
Currently unused, this is prep work for later.

For testing it's a lot easier to just provide a /tmp/ directory than having to
clear out the normal one that may contain useful drawings for debugging.

Regression introduced in e1a3675439
Where a device has no config entry, the e1a367 change would return early. This
is fine for devices previously seen and still lingering in the config but for
completely new devices, we'll never get past that KeyError.
Return to the old behaviour: where we don't have a stored UUID we continue
with the None UUID.

We want the most-recent drawings up the top. And since we always add to the
flowbox, we need to reverse-sort everything.

If we have more data than our packet [1], let's not return the whole data
array. Slice it to size instead.
[1] this never happens with the current code, we don't work asynchronously

we don't need the same-ish check twice, we can just pop our non-list into a
list an go from there.

This requires adjusting the svg conversion in kete as well, afaict the 1000
range there was chosen because it's (almost) the midpoint of the Bamboo series
with 2048 pressure grades. So let's use half of 0x10000 instead, which is
approximately 0x8000 as the crow flies.

This is using opacity of 0% to hide them - this way the space stays allocated
and showing it doesn't rearrange things. Using visiblity here causes
everything to shift around on reveal.
The default size of the drawings is a bit small now, good for an overview but
not for identifying which drawing to use now. Add a zoom slider for that.
