Describe the bug
-"tidal_resource" variable is required always in mhk_tidal cmod, even if model choice is set to time series data
-Fix memory allocation to account for tidal_resource and time series options
-See #1275

Expected behavior
-tidal_resource only required if tidal_resource_model_choice=1
-Number of rows based on power_curve if resource matrix is not provided (maybe always based on power curve)
