NodeJS v12 compatibility

[goooseman]

ref package does not work with NodeJS v12 and will never be: source

This PR updates .nvmrc to NodeJS 12 and uses ref-napi libs family instead of ref to resolve the issue.

Two type definitions are added to the project, which will be removed after this and this PR's will be merged and released.

This change is tested with NodeJS 12.13.0, MacOS 10.13.6 and my Canon 80D. Everything works as before.

The example folder is a broken at the moment, because it attempts to install an old ts-gphoto2-driver version and it fails, because of ref module can not be compiled under NodeJS v12. I suggest to release a 2.4.0 version of this lib and bump the dependency version in examples/package.json after.

The build is failing, because examples/package.json installs "@typedproject/gphoto2-driver": "2.2.3", which uses ref, which fails to build under NodeJS v12.

Will be resolved after release, by bumping the dependency version in examples/package.json

Good idea :) but, I have a doubt when the npm package will be released. Theses files won't be packaged. It means theses types won't be available when a developer install our package.

I think to fix it, you have to move this files in src/@types and import it in index.ts? Why do you think ?

[goooseman]

I'll try it out right now.

[goooseman]

Ohhhh, I didn't see you forced push and I've pushed again.

Can you please make a force push again from your local branch without pulling the changes from remote? This will fix the issue.

BTW, moving @types to src/@types and importing in index.ts works and sounds like a great idea

[goooseman]

Ok, I've resolved the git issue and moved @types to src

[Romakita]

Nice :). I'll merge your PR

[Romakita]

Release is on going :)

[Romakita]

Released :)
