Feature Request: Crop

[hpssjellis]

The camera is working very well using the Nano33BleSense, just wondering if the library already has the ability to crop images. My working output is 160 x 120 x 2(bytes), but for many machine learning applications the output needs to be square so 120 x 120 x 2(bytes). I am trying to write the cropping code directly but wondering if it is already buried within this library?
