Added SU information each remaining SUs

[QuanMPhm]

Closes #16. This is one of two solutions I am proposing, where the SU definition for each SU is contained in a single string with the format below:

"vCPU ,RAM , vGPU "

The other solution is #18

A sample code to retrieve SU information would look something like this:

su_names = ["GPUK80", "GPUA100SXM4", "GPUH100", "CPU"]
su_def_delimiter = ","
su_def_dict = {}

nerc_data = load_from_file()
for su_name in su_names:
    su_def_dict.setdefault(su_name, {})
    su_def_list = nerc_data.get_value_at(f"{su_name} SU Definition", "2024-12").split(su_def_delimiter)
    for su_resource in su_def_list:
        su_resource_split = su_resource.split(" ")
        su_def_dict[su_name][su_resource_split[0]] = su_resource_split[1]

I don't like this solution because it makes the "value" field effectively an unstructured string. It's no longer possible to apply any sort of schema validation to it.

Abandon this in favor of the other approach.
