Settle on a final project name

This issue serves as a reminder that "ExIntegrate" is a codename and subject to change leading up to the initial release. It would be good to have the final name nailed down by then.

@garrettmichaelgeorge feel free to suggest what you think it should be

@samrose I don't have any brilliant ideas yet! We could have a brainstorming session sometime.

Actually one thought is that if this project is intended to be useful to projects outside of the BEAM ecosystem, it may be better to drop any reference to our implementation language (Ex–).
