Date slider should reflect temporal linearity
Check in the dataset the version of flatsim, if it matches a version that store the date in the description field of the band, then use it as date (like it is already the case). When dates are provided, the date slider should reflect the time gap between bands (12 days should be represented as a gap 2 times bigger than 6 days for example). Also always give the option to use the date slider as a band number slider (like currently).
