feat(#64): Omit XML Header in Xembler Output

[volodya-lombrozo]

Omit the following XML header in Xembler output:

<?xml version="1.0" encoding="UTF-8"?>

To do so, we now can use the following:

new Xembler(directives, new Output.Node()).xml();

Closes: #64.

@yegor256 Could you take a look, please? I need that feature in other project.

[yegor256]

@volodya-lombrozo maybe it's better to move the creation of Transformer into this new object too? And rename it to Tranformers. Then:

interface Transformers
  Transformer create()

class DefaultTransformers implements Transformers
  Transformer create()
    // here we just create it

class FormattedTransformers implements Transformers
  Transformers origin;
  Transformer create()
    // here we set properties

Then, by default Xembler will encansulate new FormattedTransformers(new DefaultTransformers()). But for your specific case, you will instantiate it only with new DefaultTransformers. Vertical decorating, so to speak: https://www.yegor256.com/2015/10/01/vertical-horizontal-decorating.html

@yegor256 Could you take a look one more time, please?
