Revise CPAP/APAP identification in SleepStyle loader

Browse Source 
o While the Sleepstyle summary record has a data item that appears to identify the mode as CPAP or APAP, it is not reliable
  o Determine APAP or CPAP by comparing Max and 95 percentile pressures seen with the CPAP pressure setting
  o This could result in an incorrect identification if user sets CPAP pressure to APAP Max pressure.
  o Add DEBUGSS define to enable SleepStyle loader debugging.
