creating a de_interleave(s,k1,k2,orien,height,width): outside of fwt97_2d(m,
    if orien is false the image will appear as the  Paper_30-FPGA_Implementation
    The inverse is still not good.
    k1 and k2 were modified from k1 = 0.29 k2 = 0.13 to k1 = 0.9 k2 = 0.013
    removed intbv with no difference in results
    add floor function.
