Have an unique id for the data

[Trudill]

It could be interesting to have a unique ID for the data and be able to show it the same way as {lat} and {lon}.

So that if we have a collaborative map, we can identify the data easily, to report it for example.

If we export the data and use it for another purpose, it may also be useful.

As the data are stored in row, it could be the row number, but it may change if a row is deleted. An unchanging ID may be more convenient if the data is also use somewhere else.

Thank you for UMAP !
