:arrow_up: Upgrade all dependencies

[quilicicf]

There was a vulnerability on a dependency, seeing that almost all dependencies could use a bump I upgraded them all in the process.

The tests pass on my machine, let's see if they do on CI.

If you could release cpx when this gets merged it would be awesome :pray:

I checked why the tests fail on CI.

They do fail on NodeJS 6.5 because there are some rest/spread operators which are not supported in this version of NodeJS.

I didn't add them so I'm not sure how I should fix them (or even if I should do it).

Looks like there are two alternatives:

• remove support for NodeJS 6.5, which is not supported anymore (I could do that easily)
• revert the changes that broke the build on NodeJS 6.5 (but I suppose they were added knowingly and is not the way forward?)

Just tell me :)

I'd really appreciate if this gets merged. Unfortunately this project hasn't been updated in a while. Hope it's not dead.

[quilicicf]

Well if it is dead I might fork it but the support will be minimal, I don't know the code base at all....

@mysticatea Are you still maintaining this?

[matthias-ccri]

@mysticatea might be dead too

Someone seems to have developed a maintained replacement (cpx2).
