EL1252 m0s002-BI01-TimeRiseTS pv only post output event when nanosecond counter change

[anderssandstrom]

You would expect the output event to be triggered for every new timestamp and not only when the nanosecond part is updated.
I noticed this issue when sampling digital pulses in 1Hz.
Possible solution:

• Put second value in VALA
• Put nanosecond value in VALB
• Set EFLG to "ALWAYS".
• Keep nanosecond in VAL or replace with just a integer counter counting executions.
  @kivel What do you think?
