Dew point algorithm does not return correct value

[oyve]

ACTUAL:
environment.outside.temperature | 305.9 (K)
environment.outside.humidity | 60.288 (RATIO)
environment.outside.dewPointTemperature | 401.05639938388276 (K)

EXPECTED:
outside.dewPointTemperature should be closer to 297 (K)

A fix could be to use a weather formula library I created some time back, and who supports several different algorithms and picks the best one based on different input ranges.
