Maximum Number of Visible Points

Given integer points, an integer angle (0 ≤ angle < 360) and your location, return the maximum number of points you can see at once through a field of view angle degrees wide that you may turn to face any direction; points on its edges count, and points at your location are always visible.

[[2,1],[2,2],[3,3]] a=90 @ [1,1]

[[1,0],[2,1]] a=13 @ [1,1]
