Add scripts "ciao_img_rotcrop.sh" and "ciao_mkimg_det.sh".
Writen for ZHANG Chenhao to generate rotated and cropped image for power spectrum analysis. WARNING: the image generated by "ciao_mkimg_det.sh" in the DET coordinate is very different than that in SKY coordinate. Watch out for scientific usage!!!
