Skipping v1.6.3 to move directly to v1.7.0

[jnaulet]

There will be no v1.6.3, branch v1.6.x will be left as-is, as a new major revision will arrive soon that will make it dead on arrival.

The new major (and maintained) revision will be v1.7.x, that adds support for shared priorities (round-robin scheduling).
This version will be compatible with the existing API, with only one exception, the SMP call picoRTOS_SMP_set_core_mask() has been replaced by a much more logical picoRTOS_SMP_add_task()

So if you use, this call, you will have to make a small fix to your code (nothing major).

Anyway, i'm still working on it, stay tuned
