chore: use node 14

[chmelevskij]

This is matching PR to use node 14 similar to how it's done in configurator. This also adds .nvmrc and engines to match the configurator.

Have you tested if video playback is working with the new node version? This is often the sticky point for version compatibility with blackbox explorer, as external codecs are used.

I've tested it under Windows and it seems video playback works. I'm not totally sure because it is not too smooth but I think this happens too with older version.

@chmelevskij please rebase. I think this should be merged soon to be in sync with configurator.

@chmelevskij it would be great to action this - any chance you could review the conflicts and re-check it is OK?

[chmelevskij]

Hey, will try over the weekend. Want ot match the setup with configurator first.

[chmelevskij]

Updated with changes from configurator still need to verify the builds though.

[haslinghuis]

@chmelevskij it's not building. Any update on this?

[haslinghuis]

@chmelevskij seems some commits don't belong here?
