/**
 * getDeepestSplits will take an array of strings like an array of deep object keys and return the set of keys at particular depth.
 *  The point of the function is to get the deepest key of something like a deep object property for table heading labels for EasyAnalyticsHook.
 *
 * for instance deepKeys = [ 'a.b.c', 'w.x.y.z', '0.1.2.3.4.5' ]  and assuming delim = '.'
 *
 *    if idx === 0  : result: [ 'a','w','0' ]
 *    if idx === 1  : result: [ 'b','x','1' ]
 *    if idx === 2  : result: [ 'c','y','2' ]
 *    if idx === 97 : result: [ 'c','z','5' ]
 *
 * @param deepKeys
 * @param delim
 * @param idx
 * @returns
