"float" type should be "number"

[danfowler]

{
    "name": "latitude",
    "description": "",
    "type": "float"
},
{
    "name": "longitude",
    "description": "",
    "type": "float"
}

should be:

{
    "name": "latitude",
    "description": "",
    "type": "number"
},
{
    "name": "longitude",
    "description": "",
    "type": "number"
}

Thanks @danfowler . Along with #100 (and any other issues you find!), I'll update the documented version of the spec that we're working with in https://github.com/openreferral/specification/blob/updated-documentation/datapackage.json to take account of this, if @timgdavies doesn't get to it
