Create data object for D-Flow FM Time Dependent Roughness netcdf files

[erikpelgrim]

Example config for new data object:

<dataObject className="org.openda.model_dflowfm.DFlowFMNetCDFSampleFile">
    <file>%frictionCorrectionFile%</file>
    <id>frictionCorrection</id>
    <arg>idPrefix=%frictionCorrectionPrefix%</arg>
    <arg>netCDFvariable=phase</arg>
    <arg>netCDFvariable=amplitude)</arg>
    <arg>timeconstant, timeindependent</arg>     
</dataObject>
