Support what versions of es on node/browsers?

https://github.com/canvg/canvg/pull/653 has some discussion

Generally:

• What node versions do we want to support?
• What browsers do we want to support?

This will take effect in the 2.0 release.

My suggestions:

• Drop support for node <6.x and bump to node 8.x so we can use es6/async/await natively. node 6 is almost at end of LTS anyways.
• Target es6 for browsers http://kangax.github.io/compat-table/es6/. IE11 no longer supported.

i’ve used browserlist in the past and didn’t know it worked for node so let’s just do that.

let’s do one build for each of the following:

• node 8.x+
• browserlist defaults (will be strictly for ie11 probably, but can also have users compile this themselves)
• browsers that support es6 modules

how’s this work for you?

agreed. our targets are well defined today and people can open PRs if they want different support.
