seqio 0.0.13 cannot be installed on Apple Silicon due to transitive tensorflow dependency of clu

[tuzhucheng]

db4d4b0 added clu as a dependency of seqio.

With this change, we can no longer install seqio on Apple Silicon machines (e.g. M1, M2). This is because clu requires tensorflow (https://github.com/google/CommonLoopUtils/blob/85f9d28556f2684e2c5f2e412cbef5119d6682ba/setup.py#L54) but on Apple Silicon tensorflow should be installed as tensorflow-macos based on the instructions at https://developer.apple.com/metal/tensorflow-plugin/.

A simple fix is to update the clu tensorflow line in the setup.py to tensorflow; platform_machine == 'x86_64'. However, that project doesn't accept GitHub issues or contributions so I am creating an issue here.
