Create a CDEvents CLI

[erkist]

Pick one of the SDKs and develop a CLI for it which allows terminal users and scripts to send events without directly integrating with any of the SDKs.

The Go SDK used to have a CLI (so did the Python SDK) but in their current version none of the SDKs provide a CLI.

Go SDK tends to be faster with adopting new spec changes, but may be slightly trickier to build and distribute?
Python SDK can come with a CLI that can be distributed via pypi, but it won't be much value if it is often out-of-date.

Thoughts and ideas?
