Add seamarks (buoys) for Buck Island and Buck Island Reef National Monument from https://navcen.uscg.gov/sites/default/files/pdf/lightLists/LightList_V3_2023.pdf.

For instance this note's location should be near "Channel Buoy 2" which is a red Nun buoy which denotes starboard (right) side of the channel when entering the lagoon.
