Feature request: support SIGMA BF “SIGM” atom in MOV files

[A-TAK]

Hi Phil,
I hope you're doing well! I wanted to reach out with a heartfelt thank you for the incredible work you've done on the SIGMA BF support in ExifTool.
I'm happy to report that the additional MakerNote tags (PictureModeStrength, Fade, and Vignette) are working perfectly in the latest release. I've tested them with my SIGMA BF files and can confirm that these parameters are now being properly decoded and displayed correctly.
ExifTool continues to be an absolutely indispensable tool, and your dedication to continuously improving it is truly appreciated. Thank you once again for all your amazing work and for maintaining such a fantastic resource for photographers and developers worldwide.
Best regards,
A-TAK
