Implement routine to transform brcode strings into objects (parser)

[hiagodotme]

For the next versions, I believe it would be useful for a routine to do the reverse process. In other words, transform brcode strings into objects.

[hiagodotme]

The implementation was started at the branch brcode-parser.

@andersoney example:

const brcode = '00020101021126970014br.gov.bcb.pix0136fcba8826-cbff-46e2-8c40-1b39896402a80235Donation with defined amount - GPIX52040000530398654045.005802BR5917Hiago Silva Souza6009Rio Preto610815082131620705031236304520D';

// parsing brcode
const pix = PIX.parse(brcode);
console.log(pix.getReceiverName());
