AFTC for bi record

The bi record now also supports the AFTC parameter. The AFTC field sets the time constant on a low-pass filter that delays the reporting of limit alarms until the signal has been within the alarm range for that number of seconds (the default AFTC value of zero retains the previous behavior). One has to make sure that the bi record is processed at a reasonably fast rate when using AFTC, so that the record can respond to changes in the input signal within the time constant.

AFTC and LALM fix for mbbi record

Fixed two issues in the mbbi record where the AFTC and LALM fields were not operating as expected.
