docs: Configures the marshaller used to serialize actual value sizes to off-heap memory in maps,
  created by this builder.
  <p>
  <p>Default value size marshaller is so-called "stop bit encoding" marshalling, unless {@link
  #constantValueSizeBySample(Object)} or the builder statically knows the value size is
  constant -- special constant size marshalling is used by default in these cases.
  
  @param valueSizeMarshaller the new marshaller, used to serialize actual value sizes to
