Efficient coordinate collection from LineStrings using reinterpret

    end
end # median time 3ms v/s regular parsing 300ms

# parse the whole linestring
@benchmark collect(reinterpret(Tuple{Float64, Float64}, view($ls_as_wkb, (1+4+4+1):length($ls_as_wkb))))
# median time 290ns vs unknown (still running) 
# we could even drop collect here
