The dictionary of strings was taking a lot of space, and is now replaced
by a binary tree flattened into a string plus a small loookup function.

Experimentally drop the HGAIN to x8. Currently the evidence base for
this change is a little weak but it doesn't seem to be *worse* than
what we have now. Therefore I hope the wasp-os users will forgive me
for using them as guinea pigs!

Currrently, gcc-11 users risk bricking their devices because to the
combination of a new optimization pass and some mistakes in the way
the Nordic Softdevice headers wrap the SD system calls.

When I created the weather app I didn't have GadgetBridge installed, so I tried to follow the protocol on the [espurino website](https://www.espruino.com/Gadgetbridge), but it wasn't very helpful and I made some mistakes. This commit should fix these mistakes to stop the weather app from crashing, and so it displays the correct values. I have also added a new settings option called "Units", where apps can see what units the user would prefer (metric/imperial).

Testing has demonstrated that del self.x does not make the memory used to
store x available for garbage collection.
There is clearly an additional reference from another place. In fact
*after* del self.x then the memory can be made available for GC by
assignment (e.g. self.x = None). However I haven't found how to release
this reference and there is nothing in self.__dict__ that can help.
For now we'll use a twp-step process where we set the variable to None
before deleting it.
This has a big impact on memory usage. For Software it is almost 1k
(a.k.a. about 10% impact on free RAM).

Currently the final word of wrapped text will always appear as a single
word on its own line. Fix this by rearranging the break cases to avoid
searching for the most recent space when we get to the end of the text.

Reduce the number of applications imported by the manager and alter
the way applications are initially registered to allow main.py
complete control over the initial applications (but only if it wants
it).

Many widgets adopted the _im(mutable) idiom to allow us to reduce the
RAM overhead of each widget. Where the immutable data considers entirely
of integers smaller than 256 then we can push this just a little further
by switching from a tuple to a bytes.

Currently the ChronoApp example code is both broken (missing apps. prefix)
and doesn't use the latest API for registering watch faces. Fix this.
Whilst here let's also provide an example for the DemoApp since that
is not included in the Software chooser.

The demo app is of somewhat niche interest and is disabled by default
but arguable that makes it more important to document it fully since
this app is harder to find the many others.

One benefit from wasp-os' dirt simple drawing model is that it is very
easy for apps to provide full screen previews of themselves. Add this

So... waking up once per second turns out to be a dumb idea because it
regresses the stop watch and HRS tools (which now also only wake up once
per second).
Undo this change but sprinkle a few more micropython.native decorations
on methods used on the wakeup path to minimise power.

Currently the time is calculated 8 times per second from (relatively) slow
python code. Optimize the power consumed by reducing the number of times
we check for wall time updates to only once-per-second and use native
code generation to reduce VM overhead when executing this critical code.
At the time of writing the difference is battery life has not yet been
measured (but we know the current master branch is worse than v0.4 and,
in theory at least, this should close the gap).

wasp-os uses an drawing optimization technique to automatically place
a single pixel line on the right of glyphs when rendering them. This
results in a change to the bounding box for a rendered string (by adding
a single pixel on the right of the final character). Fix the bounding box
calculations accordingly. Among other things this eliminates graphical
artifacts when rendering labels in 2048.

When an application is registered using a string that gives the class
name (e.g. "apps.chrono.ChronoApp") when we automatically delete
the module from a couple of namespaces. This ensures the garbage
collector can do a deeper clean when the application is unregistered.
We also provide a means to directly register watch faces (e.g. to
replace the default clock).
