add_srml_to_AOIs, add_tokens_to_AOIs are not extendable for future datasets

[quanphan2906]

These functions manually matches the name of the stimuli with the name of the original code file, from which the stimuli was adapted. An example can be seen below (this is taken from add_tokens_to_AOIs):

EMIP-Toolkit/emip_toolkit.py

Lines 1222 to 1245 in d1a7eab

	if image_name == "rectangle_java.jpg":
	file_name = "Rectangle.java"
	if image_name == "rectangle_java2.jpg":
	file_name = "Rectangle.java"
	if image_name == "rectangle_python.jpg":
	file_name = "Rectangle.py"
	if image_name == "rectangle_scala.jpg":
	file_name = "Rectangle.scala"
	# vehicle files
	if image_name == "vehicle_java.jpg":
	file_name = "Vehicle.java"
	if image_name == "vehicle_java2.jpg":
	file_name = "Vehicle.java"
	if image_name == "vehicle_python.jpg":
	file_name = "vehicle.py"
	if image_name == "vehicle_scala.jpg":
	file_name = "Vehicle.scala"

This needs to be refactor to make the two functions extendable for future datasets.
