docs: def is_corrupted(l, sym, input_v):
      """
          This method can be used to check for a corrupted version.
          Will continue to a full read (slower) if the internally invoked fast-detection does not locate a corruption.
  
          Parameters
          ----------
          l : `arctic.store.version_store.VersionStore`
              The VersionStore instance against which the analysis will be run.
          sym : `str`
              The symbol to test if is corrupted.
          input_v : `int` or `arctic.store.version_store.VersionedItem`
              The specific version we wish to test if is corrupted. This argument is mandatory.
  
          Returns
          -------
          `bool`
              True if the symbol is found corrupted, False otherwise.
