Update PlanetScope scripts (#308)

* PlanetScope true color: use dataMask to make no-data pixels transparent

* PlanetScope false color: use dataMask to make no-data pixels transparent

* PlanetScope NDWI simple visualization: use dataMask to make no-data pixels transparent

* PlanetScope NDWI raw values: add script

* PlanetScope NDWI EOB visualization: add script

* PlanetScope NDWI: add scripts to readme.md

* add dataMask only at the end for PS NDWI script

* rename samples to sample in PS NDWI script

* remove unused dataMask band in PS NDWI raw script

* avoid returning infinite number in  PS NDWI raw script

* rename samples to sample in PS NDWIeob script

* add dataMask only at the end for PS NDWI eob script

* avoid returning infinite number in  PS NDWI eob script

* rename samples to sample in PS NDWIraw script

* improve eob script for PS NDWI
