Allow to initialize $

[gajus]

The current API feels awkward, whereby settings are applied after the command, i.e.

$`date`
  .nothrow()
  .quiet();

I'd like to be able to do something like

const $ = createZx({
  nothrow: true,
  queit: true,
});

$`date`

I believe v8 will bring smth similar. Here's a proposal:

• https://github.com/qiwi/zx-extra/blob/master/src/main/js/index.mjs#L40
• https://github.com/qiwi/zx-extra#opt

Yes, I'd like to refactor the api to allow more easy customizations.

$({nothrow: true})`cmd`
