scaleX, scaleY, rotate, & more multiplatform targets

• update to kotlin 1.9.20
• add more multiplatform targets (linux, mac, windows, IOS). Android is to be done as it requires an additional plugin.
• implement scaleX, scaleY, and rotate functions for geojson that works for Geometry instances, Features, Feature collections, and the various coordinate arrays.
• fix bug with centroid implementation to use the min/max divided by two instead of the mean of the coordinates.
