Improved Paging process, speed and reliability

[hllhll]

This PR improves the reliability and performance of the PAGING process when connecting to another Bluetooth device. This is done by 3 parts

1. Sending the page/ID(1) message 2 times within each master's tx window instead of once
2. Change the frequency iteration logic to, hopefully improve performance for devices that are not continually scanning. I.E. Their SR/scan repetition might be R1, R2
3. Implemented the logic in which if we "hit" the right frequency once, but failed to complete the process (receive ID(3)) retry for the time period given in the Bluetooth spec before giving up and continue to iterate other phases of the clock.
