// Buffer sets the initial buffer to use when scanning
// Buffer controls memory allocation by the Scanner.
// It sets the initial buffer to use when scanning
// and the maximum size of buffer that may be allocated during scanning.
// The contents of the buffer are ignored.
//
// The maximum token size must be less than the larger of max and cap(buf).
// If max <= cap(buf), [Scanner.Scan] will use this buffer only and do no allocation.
