Convert negative precipitation rates to 0 (NGWPC-7450)

[idtodd]

LASAM expects the set precipitation rate to be a positive number when Update() is called. It was noticed that snow17 may pass its melt and precipitation delta as a negative number to LASAM, causing LASAM to throw an error. The update prevents the error from being thrown by checking if the incoming precipitation rate is less than 0 and interprets it as 0 instead.

Additions

• Convert negative precipitation rates to 0 in SetValue.
• Warning level log when the value is set to 0 to record what the original value is.
