Binary adjacency matrix for neastdata

Description

A matrix indicating the binary adjacency matrix for the neastdata. Some of the islands (e.g., Nantucket) are considered adjacent to the mainland because of ferries traveling from certain mainland regions to these islands. Manual connections were added for many of the New York counties because they are on islands. neastw_old is an old version included for backwards compatibility. neastw_old and has some imperfections related to symmetry and does not have as many connections for the New York counties.
