[models] Validate DSS model at creation time

[RustedBones]

Is your feature request related to a problem? Please describe.

There is no validation when creating a DSS model (Volume4D/3D). Invalid models are detected when executing some operations lilke CalculateSpatialCovering.

Describe the solution you'd like

Prevent creation of invalid DSS model to handle errors early on durion conversion from the API

This will allow to:

1. Factorze some validation made in the API
2. Operation on the model can assume its correctness and skip validation

Describe alternatives you've considered
Have a IsValid method receiver on the model for validation called by all model operations
