Delete Employee File

Deletes the specified employee file. The special employee ID of zero (0) resolves to the employee associated with the API key. Successful deletions are idempotent: if the file was already deleted for that employee, the endpoint may still return 200. Returns 404 when the file is not associated with the specified employee, 403 if the caller lacks permission or the file is managed by BambooPayroll, and 500 on an internal error.
