Subject: [PATCH] Fix broken assertions in RadarPointCloud PCD header parsing

- Fix height assertion error message: said "height != 0" but the check
  is "height == 1", so the message now correctly says "height != 1".

- Fix COUNT assertion: the expression `c != c` is always False for
  strings, making the assertion a no-op. Replace with an explicit check
  that all COUNT values equal 1, since multi-element fields are not
  supported by the binary parser below.
