add parser for saved places on google maps

[karlicoss]

Seem to be scattered across different formats 💩

"Saved" list is in "Maps (your places)/Saved Places.json" -- present since 2015

{
  "type" : "FeatureCollection",
  "features" : [ {
    "geometry" : {
      "coordinates" : [ -0.1202100, 51.5979200 ],
      "type" : "Point"
    },
    "properties" : {
      "Google Maps URL" : "http://maps.google.com/?cid=17295021474934382781",
      "Location" : {
        "Address" : "United Kingdom",
        "Business Name" : "Alexandra Palace",
        "Country Code" : "GB",
        "Geo Coordinates" : {
          "Latitude" : "51.5979200",
          "Longitude" : "-0.1202100"
        }
      },
      "Published" : "2017-09-27T09:56:06Z",
      "Title" : "Alexandra Palace",
      "Updated" : "2017-09-27T09:56:06Z"
    },
    "type" : "Feature"
  }, {
    "geometry" : {
      "coordinates" : [ -0.1307733, 51.5941783 ],
      "type" : "Point"
    },
...
]}

Whereas other lists are in CSV files (since 2018), in "Saved" directory, one for each list in google maps
e.g. Saved/Paris.csv

Urfa Durum,,"https://www.google.com/search?q=Urfa+Durum&ludocid=15623525448940569321&ibp=gwp;0,7"

doesn't seem like this data is preset anywhere else in takeouts
