Add support for nested attribute properties

The goal for this enhancement is to provide the ability to ‘flatten’ properties from the input into primitive attributes. For example:

data = {
  lat: 12.34,
  lng: 56.78,
  info: {
    name: 'Johnny Goode',
    age: 12
  }
}

GeoJSON.parse(data, {Point: ['lat', 'lng'], include: ['name']});

There is currently no way to get the ‘name’ property as an attribute of the resulting GeoJSON object.

In an attempt to avoid breaking existing logic, I think this may be a good solution:

function getPropFunction(params) {
  ...
  else if (params.extract) {
    func = function(properties) {
      ...
    }
  } else if (params.include) {
  ...
}

@longbuibao Hi there! This functionality has not been implemented yet. I found a different solution to this problem in my code and did not circle back to this enhancement. If you want to try and implement this, I’m sure @caseycesari would welcome a PR!

I will try sir! 😂 I’m new to programming so I think I dont have enough experience to read code 😂

btw my solution is pull out the property…thank you for great npm module!
