Two problems have been identified for spectral dfsu files in the Hm0 calculation:

deletevalues in spectrum will give nan Hm0 - it should be safe to treat them as 0
if the file uses radians instead of degrees (unit: meter pow 2 sec per rad), the directional integration is wrong and Hm0 results will be sqrt(180/pi) too large.

def calc_Hm0_from_spectrum(

and related functionality is actually out of scope for MIKE IO?
