convert to ESM

[milahu]

ESM is required for top level await

if (process.argv[2] == "install") {
  (await import("./native-autoinstall.js")).install();

this is a by-product of my attempt to fix

  // note: this disables the exception handler
  // so exceptions will silently fail
  // for (let e of ["exit", "SIGINT", "SIGTERM", "uncaughtException"]) {
  converter = await import('./converter.js');

importing converter.js on the top level disables the exception handler

Sorry for the late reply.

That's great! Does it work proper with an older version of Node (version 10)? We sadly have to support old Node for older OSes.

sorry, but for me thats out of scope

Yeah, to drop Node 10 support, we would have to also drop Linux 32bits, Windows 7, and MacOS 10.13.
