Now that the post-process calcLeaks properly handles discontinuous
data, don't make the loader pretend that the machine generated
CPAP_Leak data when it didn't.
The resulting data is nearly identical, except for around edge cases
where the "correct" result is isn't clear. For example, when a
pressure changes within a 2-minute reporting interval, the
post-process calcLeaks will use that pressure when calculating
the unintended leak for that interval. The previous PRS1 loader
calculations were inconsistent, but would often apply the pressure
in place at the beginning of the 2-minute interval instead.
Either interpretation could be reasonable, but consistency is
preferred.
These minor differences aren't worth pursuing further, since the
calculated unintended leak looks dubious regardless.
This affects all CPAP/APAP/BiPAP models in the 4xx-7xx range.
In contrast, most ventilators and ASV record unintended leak
data (only the oldest ones don't), and so aren't affected by
these changes.
