Fix npm run test in run pkg (a typescript error)

[mjyc]

make test run fails with some typescript errors, but using the cycle-robot-drivers/run package in javascript works.

I suspect the problem is originating from 3rdpart/cycle-posenet-driver pkg.

It turns out some dependent pkgs of @tensorflow-models/posenet were not using a consistent typescript version, e.g.,

https://github.com/tensorflow/tfjs-core/blob/v1.0.4/package.json#L45
but
https://github.com/tensorflow/tfjs-models/blob/master/posenet/package.json#L32
and also
https://github.com/TypeStrong/tsify/blob/master/examples/babelify/package.json

I'll wait for tensorflow/typescript updates.
