Support saving and loading trk/trks data to/from `BytesIO` @msschwartz21 (#68)

In the data-registry, we often read and write track data in memory in order to facilitate moving data to and from s3 buckets. This PR enables a io.BytesIO() object to be passed into save_trks and load_trks in place of a filepath. Additionally a new utility function save_track_data is introduced to serve as a base for save_trks and save_trk which are wrappers that allow saving to either trk or trks.
