Request WPTO fails with `omni-directional_wave_height`

[simmsa]

Specific issue is here: https://github.com/MHKiT-Software/MHKiT-MATLAB/blob/e780f1c13680d74d22c68be092634c3da5d1e527/mhkit/wave/IO/hindcast/request_wpto.m#L117-L118

Anticipated fix is to remove dashes from parameter(z):

sanitized_parameter = strrep(parameter(z), '-', "_");
data(y).(sanitized_parameter) = param.value;
