> When an Area Of Interest (AOI) is specified by a call to {{GridGeometry.derive().subgrid(…)}}, the current implementation requires that the AOI has at least as many dimensions as the original grid, because the result of this operation is a grid having the number of dimensions of the original grid. The problem is that we sometime have a two-dimensional only AOI and nevertheless want to apply it to a three- or four-dimensional grid. Apache SIS should be able to modify the {{GridGeometry}} only in the dimensions specified by the AOI, and leave the other dimensions unchanged.
> As a special case, SIS 1.5 accepts an AOI with less dimensions if all extra dimensions have a number of cells equals to 1 (i.e., the grid is a slice). This issue is about removing that restriction.
> To reproduce (expected behavior is success, current behavior is {{OperationNotFoundException}} between “WGS 84” and “WGS 84 + Ellipsoidal height +…”):
> {code:java}
> private static void testMultidimensionalSlicing() throws Exception {
>     var sourceEnv = new GeneralEnvelope(CRS.compound(
>             CommonCRS.defaultGeographic(),
>             CommonCRS.Vertical.ELLIPSOIDAL.crs(),
>             CommonCRS.Temporal.JAVA.crs()
>     ));
>     sourceEnv.setRange(0, 10, 20);
>     sourceEnv.setRange(1, 30, 40);
>     sourceEnv.setRange(2, 0, 2);
>     sourceEnv.setRange(3, 0, 2);
>     var sourceGrid = new GridGeometry(
>             new GridExtent(null, new long[4], new long[] { 2, 2, 2, 2 }, false),
>             sourceEnv,
>             GridOrientation.DISPLAY
>     );
>     var targetGrid = new GridGeometry(
>             new GridExtent(2, 2),
>             new Envelope2D(CommonCRS.defaultGeographic(), 10, 30, 10, 10),
>             GridOrientation.DISPLAY
>     );
>     var slice = sourceGrid.derive()
>                           .subgrid(targetGrid)
>                           .build();
> }
> {code}
