v0.5.5

[ilyakruchinin]

Changes since v0.5.4

Bug fixes

• MaskEvents undercount in STR.edf — MaskEvents was set to the number of
  on/off pairs instead of the total number of on+off events. OSCAR divides
  MaskEvents by 2 to get the pair count, so the reported session count was
  half of what it should have been.
  (main/edf_gen.c)

• Repeating -120 L/min flow spikes in OSCAR/SleepHQ — BLE notification
  drops (typically every ~10 minutes) triggered insertion of SNT_MISSING
  (INT16_MIN) sentinels into BRP flow/pressure data. During EDF conversion
  these were clamped to dig_min = -1000, which OSCAR scales by gain = 0.12
  (L/s→L/min), producing visible -120 L/min spikes. Changed BRP gap
  compensation to hold-previous-value (matching the existing SA2/PLD
  strategy). Gaps are typically 200–400 ms (<10 % of a breath cycle), so the
  held value is visually indistinguishable from real data. The AS11 native EDF
  never has missing BRP data, and OSCAR has no sentinel convention for
  breathing waveforms.
  (main/session_writer.c, main/edf_gen.c)
