Analyse the viabiiity and usefullness of implenting panoptic segmentation in SITS

[gilbertocamara]

Describe the new API function requested
Garnot and Landrieu (2021) proposed an end-to-end, single-stage method for panoptic segmentation of satellite image time series for agricultural applications. The method uses the idea of temporal self-attention and combines it with semantic segmentation. The proposal should be analysed and explored to be possibly included in the sits package.
