pyside6 打开.c文件过滤注释等，保留需要的字符

需要提取.c中的配置数据，用以他用，c文件的内容简单举例如下：

#define hello 0
/////

SPICMD(0xFB);
SPIDAT(0x00);
SPIDAT(0x01);

//SPICMD(0xFB);
//SPIDAT(0x02);
//SPIDAT(0x03);

SPICMD(0xFB);    //SPIDAT(0x04);    SPIDAT(0x05);

SPIDAT(0x08);    SPIDAT(0x09);/*
SPICMD(0xFB);
SPIDAT(0x06);
SPIDAT(0x07);
*/

目的是删掉红色部分内容，保留黑色部分数据，并格式化去空格、Tab以及分行。

中间有用好多方法，最后询问了优快云的Gpt给的建议，灵光一闪，用re简单处理好了。

运行结果如下：

如此获得的数据，再进行二次提炼发送串口或者其他用途。
