This is a major overhaul from SMORE3 -> SMORE4. The associated publication is the SASHIMI 2023 paper. Below is a summary of changes: - Now a single model to do SR - Replaced EDSR with WDSR - Now estimate the residual rather than just the SR image - Algorithm to ensure the correct slice number even with pixel shuffle in WDSR - Fully training from scratch: no more pre-trained weights - Support for SLR pulse design
