Fix matching on +0.0 from Erlang/OTP 27+ warnings

[elfenlaid]

The changes fix the following warnings:

warning: pattern matching on 0.0 is equivalent to matching only on +0.0 from Erlang/OTP 27+. Instead you must match on +0.0 or -0.0
└─ lib/topo/point_ring.ex: Topo.PointRing.count_crossing/2

warning: pattern matching on 0.0 is equivalent to matching only on +0.0 from Erlang/OTP 27+. Instead you must match on +0.0 or -0.0
└─ lib/topo/point_ring.ex: Topo.PointRing.count_crossing/2

The suggested way to fix them is discussed here: https://elixirforum.com/t/inconsistency-with-compiler-warnings-upgrading-to-1-17/64209/4

regardless of the OTP version:

• if you want to match on any zero, use x == 0
