scipy dependency

[mhubii]

scipy is only used for a 2D convolution:

roboreg/roboreg/util/mask.py

Line 3 in 4bbdb51

from scipy.signal import convolve2d

One should rather implement a 2D convolution in numpy and remove the scipy dependency. See e.g.: https://stackoverflow.com/questions/43086557/convolve2d-just-by-using-numpy
