sct_flatten_sagittal changes the dynamic range of the image #83

@jcohenadad, at ISMRM you recommended we flatten the spinal cord into the sagittal plane (https://github.com/spinal-cord-7t/coil-qc-code/issues/65) for better visualization of B1+ and SNR maps. I've implemented this here: https://github.com/spinal-cord-7t/coil-qc-code/commit/e6ac4b386a33ded3614fb6ccff742dd97e1c7330

However, it appears that sct_flatten_sagittal changes the dynamic range of the image. Is this normal?

The below image shows the pixel values for reference:

Oops! not normal (I think). Issue opened https://github.com/spinalcordtoolbox/spinalcordtoolbox/issues/4548. Thank you for reporting it!
