Load timelapse images as single array using dask

[adamltyson]

Rather than loading N arrays into memory, concatenate using dask, e.g.:

import numpy as np
import dask.array as da
 
a = np.memmap('a.array', dtype='float64', mode='r', shape=( 5000,1000))
b = np.memmap('b.array', dtype='float64', mode='r', shape=(15000,1000))

c = da.concatenate([a, b], axis=0)
