Links order

Hi @jreadey! With the REST API, is there a way to request the links in a group in the same order as they were created?

Here's what I'm doing:

1. Create an HDF5 file with h5py and `h5py.get_config().track_order = True`
2. Add datasets to the root of the file
3. Load the file into HSDS with `hsload`
4. GET the links of the root group — e.g. http://localhost:5101/groups/g-db06b970-804343aa-538e-31f808-cbcb22/links?domain=/sample-hsds.h5

Problem: the links are ordered alphabetically in the JSON response.
