 * 2024-08-24:  Migrated from drillFunctions
 *    getRefinerFromField
 *
 * This takes a field value of type any (number, date, text) and a set of rules to apply
 *  And returns an array of strings that can be used for filtering.
 *  This with grouping items into smaller buckets... like 1000's instead of 1001, 1002, 1003... etc
 * @param fieldValue
 * @param ruleSet
 * @param emptyRefiner
 * @returns
