Proposal to fix some of the issues with the initial implementation
it is safer to use the status line code to print the message so
there aren't any conflicts in the LCD cursor position.
Allow inserting a byte into any position in the LCD status message
Also, add a variable to control from which index in the array
should the message start printing. This is very useful for progress
bars and messages which continually update. I think we can save some
memory by applying this to Mesh Bed Leveling later.

A partial backup is needed in scenarios where the extruder may be
parked after a print is saved. For example during a blocking wait for the user in M600
Or during a MMU error screen.
A sudden power panic at this point would previously save the parked position
into EEPROM. When the print is recovered it would print in mid air.
The filament is never in the nozzle at this point so there
should be no oozing.
When a single material MMU print, I can hear audible noise
from the motor after executing Tx code. After some timeout
(while the heaters still heating up) I can hear the firmware
disable the E-motor. But we can safely disable it immediately
after the try-load-unload sequence.

Currently we are queuing many small 2 mm E-moves until the filament
sensor triggers. We do this because we never abort any queued moves,
so making small 2 mm moves ensures we do not move the E-motor more than
2 mm past the filament sensor.
Unfortunately, when E-cool mode is enabled, the E-motor will create
audible clicking sounds (similar one hears during jam or a loose grub
screw). A workaround for this is to queue one or more very long moves.
Where very long is something of the order of hundreds of millimeters. I
have it set to 350 mm but it's just a random constant really. Keep in
mind the firmware will block too large E-moves, if I recall correctly
it was anything above > 450 mm (see PREVENT_LENGTHY_EXTRUDE)
In order to use very long moves, we must somehow stop the E-motor from
moving once the filament sensor triggers. In other words, throw away
what's left of the current E-motor move. For this simple purpose we can
use planner_abort_hard() but we must set planner_aborted to false
afterwards because the code architecture does not allow the main loop()
to run until the Toolchange command is done processing.

The fact that the relationship between
machine position and pixel index is not linear
means we cannot simply rely on comparing
the previous position to the next machine position. i.e derivative of E_AXIS
Because around the max amplitude of the triangle wave
the slope will suddenly change sign and will create a deadzone
which has width 2*mm_per_pixel.
For MMU2S this is ~10mm (or two pixels).
Instead we should split the moves.
And only plan the 2nd move once we're
at the top of the triangle wave. That way we don't really care about the position delta.
Now we just calculate the current y(x)
position relative to current position and divide by mm_per_pixel.
If there is a delta measured with unit 'pixel' then that means
its time to render the next pixel.
This solution seems to work well so far on my end.

This fixes an issue where sometimes
not all 20 pixels are rendered.
It is better to render 1 too many pixels (sometimes), rather than rendering too few.

In case we are running a retry, the firmware
should clear the old rendering before
starting on a new one
