feat: add the capacity to split a featureCollection

[12rambau]

Wheneve ryou want to perform some very large analysis on GEE you will need to trick the computer by splitting your work into smaller pieces. This method has been designed specifically for that as it allows a ser to split a featurecollection into a fixeda mount of smaller collections.

import ee, geetools
fc = ee.FeatureCollection("FAO/GAUL/2015/level0")
fc.ldc.split(2).get(1).size().getInfo()
