Corrected threshold readingmasks for Type01sensors

Issue: The upper and lower threshold reading mask(Byte 16,18)
in SDR Type01 sensors are not set under any conditions.

Fix: Setting the threshold mask based on its respective threshold
conditions.

Tested:
1.Issue Get SDR command for [u,l][c,nc] sensors.
2.Check theresponse for the bits 5,4 of Byte 16 and 18 (lower and upper)
are set correctly for respective sensors.
