The Photos upload API can take a SHA-1 hash in the HTTP header. If the
hash does not match after the final payload finishes, the API server
will return 400 error.

This feature is still experimental. It works only for single-payload
upload.

Any hash mismatch will result in the batch import request failure with an UploadErrorException.

This matches the current behavior where any network issue will raise an IOExeption and fail the whole batch.

actually `maybeRethrowFileMismatchError` (and consider moving somewhere common if this isn't specific to Photos APIs)
