[CHANGE] Add libmagic for cross check with siegfried

[steffenfritz]

Is your feature request related to a problem? Please describe.
To use siegfried as the only sourfe for file identification is not a good idea as there might be wrong identifications.

Describe the solution you'd like
libmagic can be easly added and its identification can be cross checked with sf's results.

I like the idea of including libmagic as another format recognition tool.

However, the column names such as filesfformatname would then have to clearly indicate which tool they come from.

I would also advise against evaluating libmagic and Siegfried results and postulating a common "main format" in case of recognition conflicts (or in general). That is a decision that should be made by the users.

filesfformatname is always siegfried (the "sf" infix). magic should have its own column, yes.

Check if Magika might be a useful addition, see https://github.com/google/magika/tree/main/go
