Pixel Array setter doesn't work

[jrkerns]

Setting the pixel_array attr does nothing.

See this gist for an example:
https://gist.github.com/jrkerns/eab5f5da2335572a3f0f

In the "working with pixel data" example, pixel data is modified, not replaced.

I propose a setter method for pixel_array.

I use ds.PixelData = Image.from_array(arr).tobytes()

I'm not saying it can't be done (I use numpy's .tostring() method as @darcymason shows), but behavior like this doesn't work:

new_array = np.zeros((100,100))
dcm.pixel_array = new_array
dcm.PixelData = dcm.pixel_array

You explicitly have to set it with the array:

dcm.PixelData = new_array.tostring()

This is a part of what I was looking at in #50. Most likely we will need a setter for pixel_array. I'm closing this issue and any discussion can carry on in #50.
