/**
 * Inserts `x` into `buf` at index `i` and ensures that array length doesn't
 * grow beyond max `k` items (default: unbounded).
 *
 * @remarks
 * The function will have no effect iff `i<0` or `i>=k` or `k<1`. If
 * `buf.length` is larger than `k`, only the index range [i..k) will be
 * modified.
 *
 * In benchmarking with 4, 8, 16, 32, 64 element arrays, this function is
 * consistently 7-16x faster than `Array.prototype.copyWithin()` and 1.5-2x
 * faster than `Array.prototype.splice()` (for sizes < ~32). See
 * `/bench/insert.ts`
