Get trajectory in ISMRMRD raw data file.

The trajectory in the ISMRMRD raw data file is read out [TRA].

The value range of the trajectory in the ISMRMRD file is not well defined. Here we simple normalize everything based on the highest value and ensure it is within [-pi, pi]. The trajectory is in the shape of the unsorted raw data.
