Moving rotation of chip maps into ploting

Before, the maps of individual chips of a module where rotated (and extended) during creation of the module h5 file to resemble the actual module layout. To be more standardized, the maps are now only concatenated. The rotation and extension of the maps is now placed in the plotting. To reduce memory overhead, the transformation is only performed when the corresponding plot is drawn. This is achieved by replacing the corresponding Pytables table by a class performing the transformation as soon as "[:]" is used.
