Improvements 2024_03

[mzaiss]

• fix timing of SE and RARE solutions!

• directly switch to 30 and 60 degree in RARE nospoilers

• fix export files with number of coils etc.

• -seq = pp.Sequence() to -seq = pp.Sequence(system) everywhere!, removd grad_raster 50 us also everywhere

• add T2', D, B0, B1 standard to numerical brain_cropped

• check image orientation in all NUFFT files

• if possible, put all in mr0.util, not util extra

• maybe here kspace = torch.reshape((signal), (Nphase, Nread)).clone().t(), generally use Nphase,Nphase*adc.samples?

• some solution or ex had still a 90 degree pulse instead of 5 or otherwaz round

• E files check (FOV, sim + meas + RARE energy), last rare STE and FLASH works

• eg sol F01: -space = np.flip(np.swapaxes(space, -1, -2), -2) +space = np.flip(space, -1)

• make fft consistent in all ex and all sol

• fix the dk/ mismatch, pretty much every recon has linear phase due to this! I think this could be put in the rewinder just add 0.5 here later this is 0.5/fov

• rf spoiling everywhere to 84 in playground

• in exported E01 E02 i added flair pulses, but the seq was not yet reorderd

• in scipy nufft, linear interpolation method worked better
