Update package.json engines

[david-luna]

Hi,

Latest release 2.1.0 added support for lambda streaming which is pretty neat :)

I see the package.json file declares it supports node >=6 in the engines section. But on the streaming related files the package is using globalThis symbol here.

This symbol is available from version 12.4.0 according to node.green so I guess engines should be updated. I'm wondering if there is a way to make it still work in node 6.

Thanks

Thanks for the report !
Arguably, we should probably drop support for anything <= 8, as it is starting to be seriously out of date. But I'll have a look at how we can maximize support.

What do you think of #236 ?

Hi @gpotter2,

Sorry for the late reply. The change looks neat and stills support a wide version range :)

Thank you very much!
