read/write the Athena project files
one feature that would be very beneficial in est is to >read/write the Athena project files. In fact, a large number of users in the XAS community have their data stored as list of groups in the Athena files.
A simple function to read energy and mu of groups in a .prj file would be as simple as:
from larch.io import read_athena project = read_athena('cyanobacteria.prj') groups =  for name, g in project._athena_groups.items(): groups.append((g.energy, g.mu)) return groups
