marine data directory is missing

[adthoms]

As per the TRO submission, the marine dataset has been omitted. However, all_exp_data_analysis.py retains it for analysis.

cora-experiments/experiments/all_exp_data_analysis.py

Lines 7 to 12 in a111501

	EXPERIMENT_NAMING = {
	MARINE_DIRNAME: "Marine",
	PLAZA1_DIRNAME: "Plaza 1",
	PLAZA2_DIRNAME: "Plaza 2",
	SINGLE_DRONE_DIRNAME: "Single Drone",
	TIERS_DIRNAME: "TIERS",

Further, executing python hat_experiments.py throws:

Traceback (most recent call last):
  File "/home/alex/catkin_ws/src/cora-experiments/experiments/hat_experiments.py", line 46, in <module>
    pyfg = read_from_pyfg_text(marine_experiment_fpath)
  File "/home/alex/catkin_ws/src/PyFactorGraph/py_factor_graph/io/pyfg_text.py", line 295, in read_from_pyfg_text
    f_temp = open(fpath, "r")
FileNotFoundError: [Errno 2] No such file or directory: '/home/alex/catkin_ws/src/cora-experiments/data/marine/marine_two_robots.pyfg'

given cora-experiments/data/marine is missing. @alanpapalia do you plan on adding this directory?
