Version upgrade `ndarray` from `v0.16` to `v0.17`

[jofas]

ndarray bumped its version to v0.17 two months ago. I assume you want to upgrade ndarray-conv to be compatible with the latest version of ndarray, hence this issue as a reminder. For context, this has lead to the confusion of one of your users: https://users.rust-lang.org/t/ndarray-conv-cannot-import-method-from-trait/136723.

Thank you! I've published a new version.
