Please rebuild for node 16 and release NAPI changes

[templela]

The changes have been made but a release hasn't happened yet. That would be really appreciated.

@pierrec, is there a chance to get this library for newer node version?

[jubesab]

@pierrec It would be fantastic if you could update this package to work with newer version of nodes!

[pierrec]

Hello, sorry for the late response. I am no longer using Node and not following its updates/developments anymore.
I would accept a PR though to fix this issue!

[jubesab]

@pierrec I would happily contribute but I do not have the know how, unfortunately.

@templela Can you link commits?

[Pysis868]

@templela This one? a51c9e9.
There seem to be other useful commits already added to master too, which is probably what you were referring to.
Head is 943e768.

@pierrec Can you add a tag along with an NPM package update and build included?
I have this example if it helps:
https://github.com/Pysis868/node-lz4/releases/tag/v0.6.8
I'm still trying to get it to install into the other project successfully though..
The latest version was branched, and not merged into master, so I tried to unify it all.
I only upgraded the patch version number since only project internals/dependencies were changed, but maybe could warrant minor version upgrade(s) instead.

I arrived at this issue, looking for others, because another project required this one, where the latest version is 0.6.5, but building responded with errors like this:

  lz4_binding.cc
.../node-lz4\node_modules\nan\nan_callbacks .h(55,23): error C2039: 'AccessorSignature': is not a member of 'v8' [D:\Documents\Programmi ng\Others\Internet\Programming\node-lz4\build\lz4.vcxproj]
