completely took out all of the constant correctness enahcements. Also
added a powerUp() method.

order to minimize noisy/false message reception. Removed begin call
from constructor as begin now has delay which creates timer race
initialization. The delay exists to allow for power on/reset radio
settling which can otherwise prevent CONFIG bits from holding. Added a
method to allow CRC hardware validation to be disabled. This is a
requirement for various promiscuous listening RF applications. Setting
CRC width now forces CRC hardware validation enable.

for specific pipelines per suggestion.

Initial checking of new pingpair_irq example.  Right now this is just the pingpair example but renamed.
