The original enhancement will overflow the uint range, making image standardization [0,1] ineffective. The original random brightness has a small effect.

RandomDistort存在增强后图像溢出uint的问题，这样会使得NormalizeImage不符合常规预期；RandomDistort.apply_brightness()在类的默认参数配置下起的作用很小；修改后的RandomDistort经过 ppyoloe/application/ppyoloe_plus_crn_m_80e_coco_pretrained_exdark 测试，mAP由58.1增加到58.6。
