Use of optional chaining results in errors

[Barabazs]

Hi @sindresorhus When I use optional chaining in my file (anywhere) it results in an error when running gulp-strip-debug.

node:eve unts:371
      throw er; // Unhandled 'error' event
      ^

I can confirm this problem. Any use of .? will result in an Unexpected token . syntax error.

strip-debug-cli doesn’t have the problem, though.

Maybe an update of package.json is necessary (strip-debug v5.0 -> v6.0).
