Release v1.0.1

• (@joltcoke) Fixed average and total returning null for every interval that contains a null value:
  parseFloat(null) is NaN and poisoned the sum of the whole interval (thanks to @joltcoke,
  ioBroker/ioBroker.sql#526). As the result was NaN and not null, ignoreNull could not act on it either
• (@joltcoke) Fixed min returning a wrong value if the interval contains a null, minmax losing the minimum
  if the interval starts with a null, and percentile/quantile counting a null as 0
