/**
* 針對MultiPolygon進行Buffer處理
*
* Unit Test: {@link https://github.com/yuda-lyu/w-gis/blob/master/test/bufferMultiPolygon.test.mjs Github}
* @memberOf w-gis
* @param {Array} pgs 輸入MultiPolygon資料陣列，為[[ [[x11,y11],[x12,y12],...], [[x21,y21],[x22,y22],...] ]]構成之陣列
* @param {Number} w 輸入Buffer寬度數字
* @param {Object} [opt={}] 輸入設定物件，預設{}
* @param {String} [opt.supposeType='polygons'] 輸入提取模式字串，當數據座標深度為2時，使用polygons代表每個其內多邊形為獨立polygon，若為ringStrings則表示其內多邊形為交錯的ringString(代表聯集與剔除)，預設'polygons'
* @param {String} [opt.units='degrees'] 輸入Buffer寬度單位，可選'degrees'、'radians'、'meters'、'kilometers'、'feet'、'miles'，預設'degrees'
* @returns {Array} 回傳MultiPolygon陣列
* @example
*
* let pgs
* let r
*
* pgs = [ //ringString
* [0, 0],
* [100, 0],
* [100, 1],
* [0, 1],
* [0, 0], //閉合
* ]
* r = bufferMultiPolygon(pgs, 1)
