Allow independent R calculation in countries reported by CSSE as Province/State

[3dgiordano]

Currently many independent countries or geographically distant from mainland are calculated inside the main country data.

This same problem Our World in Data was having with respect to cases and death data.
They recently began to make these data independent so that they can be consulted, and that they do not affect the statistics of the main country.

I made a program that allows you to see which countries are in this situation and can become independent of the calculation.
Otherwise you can align to the list that I shared from Our world in Data.
Our World in Data use TrackingR project, If you also separate these countries they will be able to show the R data of these countries.

Also in the example program I made them a routine to know which countries reported by CSSE are not really countries, I noticed that you have a filter but being static and as CSSE was incorporating other cases you would not be filtering them.

This change can be done by the researchers if needed. For now, we will not update the code to include these countries/territories.
