The K9 is similar to the PineTime and P8 devices but does not appear
to use the CST[78]16 touch screen controllers. At present the protocol
is not known (readfrom yields all zeros, readfrom_mem provokes an
exception) so we have a hugely limited interface consisting of the side
button and the touchscreen interrupts (in other words we can treat the
touchscreen like a second button).
Works suprisingly well considering...

All the components (bootloader, reloader, micropython) has P8 support added
some time back but without full integration at the wasp-os level. Let's
add it!

Notifier was a dumb name so make it better. Now that we have a decent
name it should be obvious how to handle the BLE connection status icon!

This requires a modified version of Gadgetbridge and currently works by
implementing the BangleJS protocol.
In Gadgetbridge ensure "Sync time" is *not* set and choose "Don't pair"
when adding the PineTime device.
This has two useful properties. Firstly it means the watch will be
maintained in the background, allowing the REPL to be used for
notifications and other updates. Secondly it will save a little bit
of power by reducing the work needed to handle spurious wake ups.

Currently the simulator relies on the keyboard to issue touchscreen
gestures and button presses. Fix this by adding swipe detection and
introducing a skin which gives us the capability to press the button
using touchscreens or pointer devices.

The algorithm is fairly crude and the GUI is pretty simple but, if you stay
still for 10 seconds, there's a good chance of an accurate pulse
reading.
Of course if you jog on the spot for ten seconds it more likely to
calculate how many steps per minutes you are performing!

This avoids an implusive change in base value and makes the waveform a
little more interesting.

The heart rate analysis step is still a work in progress but the current
app allows us to visualize the the results of the signal conditioning.

The original approach is *really* bad at drawing vertical lines (it ends
up working a pixel at a time and works the chip select for each one.
Optimize both the pixel fill and the use of the line buffer. The result
is 20% faster for quarter screen fills, 3x for horizontal lines and 6x
for vertical lines.

We also change the colour scheme slightly because the increased size of
the clock interferes visually with the main display when it is bright
white.

There nothing in the docs to give the delay time required after a
reset. Currently we use 200ms because that appears on some older
code for BMA423 but is removed in more recent drivers. 50ms is still
a long time (for hardware) and has held up in testing.

Currently there's no fancy algorithms to estimate stride length. Just
pure simple step counting directly from the hardware's "intelligence
engine".

The logo module is currently unused but it simply sits there consuming
flash. Let's shift it to the demo app to is can consume RAM instead (but
only when we upload the demo to the watch).
sx is measured in pixels (2-bytes) and len(display.linebuffer) gives
a value in bytes so the divisor isn't right.
Whilst we are here let's make sure we use integer division too.
Fixes: #18
