This PR removes the ISMRMRD dependency. ISMRMRD depends on pyxb, which is at end-of-life. Removing this dependency should help stabilize the fastMRI repository for the long run.

There is only one place we need the ismrmrd Python package: to parse the xml header in the .hf files. This update replaces ismrmrd with ElementTree, which is part of the Python standard library. I've re-run all integration tests with this update and checked that the generated dataset_cache.pkl files have identical values vs. the old version.
