updated hoku:pwsRain
1. 5 minute buffers implemented with a minute rounding to the nearest five minute integer, then used as an index to a ring buffer, each bin summing the rain and wind speed

this allows a five minute baseline for calculating avg windspeed and total five minute rain.
Windspeed is reported as an average.
Rain is reported as a rate in inches per hour. Interesting. The rainTtl is a 24 hour total so you could watch the rain pile up. the Rate puts a spike on the WU graphic so shows periods of rain and an indicator of intensity in inches per hour... it amplifies the catch by a factor of 12 since there are 12 five minute bins per hour. We only look at the current bin.

pwsRain - we saw a single noise anomaly with 288 tips in the rain gage. Anyting over 10 is an error so pwsRain disregards such anomalies and reports zero, with a #error log note. Cause unknown. maybe an arduino glitch, ...

note: it occurred while I was messing with the "argentwx.service" ,,, could have been that. don't know. it was in the serial log ... could have been affected by messing with the service.

mystery for now.
