It requires mp_hal_time_ns() to be provided by a port. This function
allows very accurate absolute timestamps.
Enabled on unix, windows, stm32, esp8266 and esp32.

The parameter order in the example for ticks_diff was incorrect. If it's
"too early" that means that scheduled time is greater than current time and
if it's "running late" then scheduled time would be less than current time.
* Fix mis-spelling of `ticks_add` in code examples.
* Be consistent about parentheses after function names.
* Be consistent about formatting of function, variable and constant names.
* Be consistent about spaces and punctuation.
* Fix some language errors (missing or wrong words, wrong word order).
* Keep line length under 90 chars.

lack anything of described in the docs.
