Add check that the photosphere bounds and dimensions match the input atmosphere

[sguillot]

In #168, it is discussed that the the strict bounds should be relaxed.

But it is important to add a verification that the photosphere bounds defined by the user must match the values available in the input atmosphere tables. Otherwise, a clear error message should be displayed.

Similarly, there should be a check that the dimensions of the photosphere match those of the input atmosphere tables.
