Integrated sizing capabilities

[andreasbastian]

This is likely the first big push after LimbForge's 1.0 MVP. The goal is to be able to upload an image of a recipient's hands into the LimbForge environment and to be able to calibrate the image using an object of known size in frame. Once the image has been calibrated, the user can then extract measurements of the residual limb as well as of the intact limb (if present). LimbForge should be able to then recommend the appropriate size of device based on this measurement. More details to follow as we develop this task in greater detail.

Longer term, this could be expanded to include sizing from scan data (ideally rectified plaster positive scans).
