add format parser

[Jiramew]

Add parser to extract value from format.
Default parser will be:

string.replace(/[^\w\.-]*/g, '') 

fix ant-design/ant-design#5178

Thanks so much

parser default value should be show in document

always, it's better to use rebase -i to merge your multiple sommit before git push 😄

I think a parser may make thing complex and would be confused with formatter.

I will check it later.

Maybe renamed parse to unformatter would be more clear?

Since formatter and parser basicly must be defined at same time. How about this one?

function formatter(value, direction) { // direction will be 'format' or 'parse'
  if (direction === 'parse') {
    return value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ','); 
  } else {
    return `$ ${this.numberWithCommas(value)} boeing737`; 
  }
}

maybe like this

props.transform = {
 formatter: value => value, // default maybe
 parse: value => value
}
