expand to multi-band images

[SuzannaLin]

Is it possible to expand the model to train on multi-band (RGBNIR) images instead of just the RED/NIR band?

Currently, the model is designed for a single band. It can be extended to multiband in a simple way, by changing the number of input channels in the first convolution (line 108 in model.py).

Notice that this is not necessarily the best way of creating a multiband model. We are going to work on that in the future.
