Access `SevenZip.Formats.InSignatureFormats`

[Matix-Media]

Hello, I am currently creating a program, and it would be very useful if the SevenZip.Formats.InSignatureFormats list would be publicly available. I do not want to rely on the file extension and rather want to use the file signature to check if a file is a valid archive. Is there any other place where I can access this information in the lib, or is there a reason for it being hidden away?
