The previous init sequence relied on the display ignoring commands if
they are sent faster than 40us. Some displays may not have this
limit.
Rework the init to make it more robust to command transmission times.
The new init should still transition the display into 4-bit mode even
if the display processes commands faster than 40us.

The digital output commands implement a subset of the software pwm
commands. Change the host code to just use the software pwm commands
and simplify the micro-controller code.

- remove lot of helper methods
- differentiate class instantiate from config or directly
- don't use 'enable' template rendering when static value is used.
- new element 'disabled'
- other internal adjustments

Don't use the reactor eventtime to schedule micro-controller commands
as that time may have low accuracy.

Writes to the max31856 chip use "burst mode", so only one address
during the initialization sequence can be sent. This fixes erroneous
"Cold Junction Fault" errors.

Add an 'mcu' option to the board_pins config and use that to specify
the name of the mcu to apply the aliases to. Support applying the
aliases to multiple mcus.
Add support for any number of options starting with an "aliases_"
prefix.

Queue updates so that delays between updates are properly applied.
This fixes macros that would blink LEDs by pausing between update
commands.

The previous code calculates each step time via an "exponential
search" followed by a "false position with Illinois algorithm" search.
Replace with a "secant method" with "bounds check" search. This
simplifies the code, improves the performance, and does a better job
of finding steps near a direction change.

When in debug output mode, make sure to register the fd correctly.
Otherwise, the poll() call will use the 0 fd which could cause random
results.

If the mcu config section is omitted, it leads to confusing error
messages. Don't default the serial config option to /dev/ttyS0 to
improve the error reporting.

It is only valid to call raise_probe() when the toolhead is not
moving. Make sure to call sync_print_time() from multi_probe_end() to
ensure that. This fixes a bug that could cause the Z axis steppers to
lose their position when "stow_on_each_sample=False".
