File hash mapping is missing from OCSF to STIX mapping

[mdazam1942]

Describe the bug
File hashes are described in OCSF fingerprint object. But it is currently mapped to a custom file extension property-

"fingerprints": {
                "algorithm": {
                    "key": "file.extensions.x-ocsf-file-ext.algorithm",
                    "object": "file"
                },
                "algorithm_id": {
                    "key": "file.extensions.x-ocsf-file-ext.algorithm_id",
                    "object": "file"
                },
                "value": {
                    "key": "file.extensions.x-ocsf-file-ext.algorithm_value",
                    "object": "file"
                }
            }

Here is a sample of OCSF fingerprint object-

{
  "algorithm": "SHA-256",
  "algorithm_id": 3,
  "value": "DDA18A0E21AE47C53B4309434CBC02AE8BF764FA83A6DEFBB719431242722AA7"
}

The algorithm and values needs to be correctly set to appropriate file hash STIX objects.
