On cold boot vbat filter too slow. #132

When a PUBLISH event happens its goes through |

at beginning do another read of Vbat and use that, so now looks like |

This worked on two systems to read a good Vbat about the threshold. The third system still read a low voltage, and three seconds later read a good voltage [2023-03-07 16:28:52] Vbat_low prev/new 3.229/4.003 [2023-03-07 16:29:04] Vbat_low prev/new 3.229/4.003 [2023-03-07 16:29:04] ---LB_PWR_USEABLE_REQ CANCELLED--Lbatt= 0 [2023-03-07 16:30:03] Vbat_low prev/new 4.003/4.003 |

for version 0.34.1-abc: on boot it checks for a slow rise time on Vbat, checks 5 times, waiting 200mS between each check, and adjusts accordingly, with an output that looks like this; |
On a cold boot, turning on the power switch, the vbat filter algorithm reports a low voltage, and the system takes some time to report a reasonably accurate Vbat
and doesn't do the initial time check on power up.
It does correct, a few pass after initialization and can be bypassed with a reset.
If there is a no clock set, RTC battery dead, it does record initial date values before it connects to NTP and updates time.
A sequence is here
