Assumes the image is written with the first dimension moving slowest.
path: the file path to the image file.
dimensions: a sequence of integer values e.g. [512, 512, 512]
interval: two sequences of integer values defining the min and max coordinates, e.g.
[[20, 0], [400, 550]]
pixeltype: e.g. UnsignedShortType, FloatType
header: defaults to zero, the number of bytes between the start of the file and the start of the image data.
Supports only these types: UnsignedByteType, UnsignedShortType, FloatType.
Returns an ArrayImg of the given type.
