Keep track of when the last restart and work updates were triggered and provide helper functions for knowing the time since then.
Set max diff on cointerra devices to 32 which is still only 11 shares per second but allows for earlier confirmation of per core hashrates.
Decrease the time we wait for unsetting a core on the cta bitmap to correspond with the lower max diff of 32.
Store and display the per core hashrate on cta relative to each work restart.
