orientation before spacing

[wyli]

Is your feature request related to a problem? Please describe.
the orientation transform should be put before any anisotropic spatial scalings
so that data from different orientations are scaled in the same axes

Spacingd(keys=["image", "label"], pixdim=(
    1.5, 1.5, 2.0), mode=("bilinear", "nearest")),
Orientationd(keys=["image", "label"], axcodes="RAS"),

should be

Orientationd(keys=["image", "label"], axcodes="RAS"),
Spacingd(keys=["image", "label"], pixdim=(
    1.5, 1.5, 2.0), mode=("bilinear", "nearest")),

this is a correct example:

Lines 302 to 305 in 7b1fe3a

	LoadImaged(keys=["image", "label"]),
	EnsureChannelFirstd(keys=["image", "label"]),
	Orientationd(keys=["image", "label"], axcodes="RAS"),
	Spacingd(keys=["image", "label"], pixdim=spacing, mode=("bilinear", "nearest"), align_corners=(True, True)),
