Add stratum share submission lag time to verbose information if it's over 1 second.
Add stratum share response lag time to verbose output if it's greater than 1 second.
Always show the stratum share lag time in debug mode.
Add OP_FAN to hf protocol header.
Add op commands necessary to control hfa fanspeeds.
Add hfa fanspeed control to try and maintain a target temperature.
Add fanspeed to hfa api output and set initial fanspeed to 10%

Choose better defaults for min/max/default fan settings for hfa driver.
Correctly measure the hfa max temp and smooth out the changes in its value.

Only perform a hfa fan speed update if we have new temps to work with.
We should retry only 3 times to get an hfa header response to init since that is more than 1.5 second of waiting.
Use increments of 10 when increasing hfa clock since it may not have 5 MHz granularity internally.
Have some leeway before starting to throttle hfa dies.
Wait for 5 temperature updates in hfa before adjusting fanspeed.
Update authors for removal of gpu/scrypt.
Try one more time to get the hfa header on init since it can take 2 seconds for all 3 boards on a sierra.
