Possibly unecessary dependency from yudai/pp on unmarshaler_test.go

[luccamendonca]

Hey!

I'm packaging a go app on Debian (kong/deck) which depends on gojsondiff.
It shouldn't be a big problem, but it introduces an indirect dependency, forcing me to also package your pp fork which doesn't seem like a great idea right now (specially because the upstream is actively maintained, while the for isn't).

Would it be okay for me to open a PR removing the dependency or even importing the upstream pp (which is already distributed on Debian)? :)

Thanks!

Hi, to expand on this issue the yudai/pp fork does not contain a LICENSE file. Unfortunately, this prevents me from using yudai/pp and all packages that (transitively) depend on it, for legal reasons.

Swapping yudai/pp for the upstream k0kubun/pp, completely dropping pp or adding a LICENSE file to yudai/pp would all be suitable solutions for me. However, I would prefer options one or two for the reasons brought up by @luccamendonca.

It would be really great if we can make this change happen. I'm also up for contributing it myself if there is the chance that you accept it @yudai.

In case someone stumbles over this: As a workaround, I added a replace directive to my go.mod file that replaces the yudai/pp fork with its upstream dependency and it works as expected.

replace github.com/yudai/pp => github.com/k0kubun/pp v3.0.1+incompatible
