 * @warning Changing this value will not only affect the RAM usage of a scene but also the size of the scene table in the flash.
 *  A scene's size can be calculated based on the following structure:
 *  Scene TLV (struct)
 *  {
 *  	2 bytes GroupID,
 *  	1 byte SceneID,
 *  	0 - 16 bytes SceneName,
 *  	4 bytes Transition time in miliseconds,

 *  	[
 *  		EFS TLV (struct)
 *  		{
 *  			4 bytes for the cluster ID,
 *  			Attribute Value List TLV (array)
 *  			[
 *  				AttributeValue Pair TLV (struct)

 *  		},
 *  		.
 *  		.
 *  		.
 *  	],
 *  }
 *
 *  Including all the TLV fields, the following values can help estimate the needed size for a scenes given a number of clusters:
 *  Empty EFS Scene Max name size: 37 bytes
 *  Scene Max name size + OnOff : 55 bytes
 *  Scene Max name size + LevelControl : 64 bytes
 *  Scene Max name size + ColorControl : 130 bytes
 *  Scene Max name size + OnOff + LevelControl + ColoControl : 175 bytes
 *
 *  Cluster Sizes:
 *  OnOff Cluster Max Size: 21 bytes
 *  LevelControl Cluster Max Size: 30 bytes
 *  Color Control Cluster Max Size: 96 bytes
