Update validation to check that file name matches id

[ibevers]

From @satra @djarecka :
"@id needs to match the filename"
"if validation is passing with this, please ask dorota to add that to the validator"

[djarecka]

should this be true for all classes or only for some specific ones, e.g. Item?

[satra]

activity, protocol, and item are the ones that use id dereferencing on github and locally, hence those.

I had this code snipper lying around on one of my repos if that helps.

import json
import os

tested = 0
for root, _, files in os.walk("schemas", topdown=True):
    for name in files:
        filename = os.path.join(root, name)
        with open(filename) as fp:
            try:
                tested += 1
                data = json.load(fp)
                if data["@id"] and data["@id"] != name:
                    raise ValueError(f"{root}/{name} does not have matching @id")
            except json.decoder.JSONDecodeError:
                print(f"{root}/{name} could not be loaded")
                raise
if tested == 0:
    raise ValueError("Zero files tested")

@djarecka did our new reproschema model solve this?
