==== Example
(use chunk-vector)
;; Create a chunk-vector that holds f32vectors with the size of 2.
(define v (make-f32chunk-vector 2))
(define index-a (f32chunk-vector-push! v (f32vector 1 2)))
(define index-b (f32chunk-vector-push! v (f32vector 3 4)))
(define index-c (f32chunk-vector-push! v (f32vector 7 8)))
(f32chunk-vector-remove! v index-c)
(f32chunk-vector-set! v index-b (f32vector 0 0))
(print (f32chunk-vector-ref v index-a)) ; => #f32(1.0 2.0)
(print (f32chunk-vector-ref v index-b)) ; => #f32(0.0 0.0)
(print (f32chunk-vector-ref v index-c)) ; undefined
