代码说明
1、image_add_text方法给图片添加文字水印方法，主要参数为：图片路径、输出目录、
水印文字、字体名称、字体大小（默认100）、文字左上角坐标（默认0:0）、文字颜色（默认蓝色）、是否需要背景（默认需要为1，不需要为0）、背景色（默认白色）。
2、image_add_logo方法给图片添加logo，主要参数为：图片路径、输出目录、logo图片地址、文字左上角坐标（默认0:0）。
3、注意logo地址如果有类似C:/这种windows盘的路径情况，需要对":"进行转义。后面验证的时候，可以看看我给的参数。
4、文件名为了避免重复，采用了uuid作为文件名。
5、图片后缀格式校验只有两种，按需添加即可。
验证一下
准备的素材如下，分别为图片与logo图
验证代码
if __name__ == '__main__':
print(
image_add_text(
'C:/Users/huyi/Desktop/1.jpg',
'C:/Users/huyi/Desktop/', '剑客阿良_ALiang', '微软雅黑', box=0))
print(
image_add_logo(
'C:/Users/huyi/Desktop/1.jpg',
'C:/Users/huyi/Desktop/', 'C\\:/Users/huyi/Desktop/logo.png', (30, 10)))
注意我给出的logo地址路径有什么不同。
