Automatic interval for seamless mode

[der-stefan]

It would be nice to enable automatic interval calculation for data lists with only one timestamp information. Example:

sample 1: features.type.time = '2019-07-01 19:20:27+02:00'
sample 2: features.type.time = '2019-07-01 19:30:27+02:00'
sample 3: features.type.time = '2019-07-01 19:50:27+02:00'

The respective coordinates for sample 1 should be kept visible until sample 2 appears (=10 minutes), whereas sample 2 should be drawn for 20 minutes. Right now I see no way to accomplish that without writing start and end value into the geojsonp file in a preprocessing step. There is no way to access the next feature element within getInterval().

As mentioned in #138 I'd like to show multiple data-points thats starts and end within a single day.
Example for a json-feature:
{ "type": "Feature", "properties": { "start": "2019-01-01", "end": "2019-01-01", "datum": "Dienstag, 1. Januar 2019", "Tatort": "Erkelenz", "Deliktsgruppe": "Volksverhetzungsdelikt" }, "geometry": { "type": "Point", "coordinates": [ 6.31559, 51.07967 ] } }

Adding an automatic one-day-interval for the playback-function would solve my problem.
