In the readme section about fileTypeFromBlob, it's stated:

[!WARNING] This method depends on ReadableStreamBYOBReader which requires Node.js ≥ 20 
and may not be available in all modern browsers.

However, the function seems to work well in Safari 18.6, despite it lacking support for said Reader.

The only dependency on ReadableStreamBYOBReader that I can find is in the strtok3 library, but its WebStreamReaderFactory.ts seems to contain fallbacks in case byob support is missing.

Is the documentation in the readme perhaps outdated? I notice the relevant section was last updated two years ago while WebStreamReaderFactory.ts was added in a big commit only seven months ago.
