Difference in detected mime-type between libmagic 5.38 and 5.40

[shuttlesworthNEO]

While running some tests I encountered a discrepancy between the expected mime type. Using libmagic 5.40 the mime type detected is application/octet-stream whereas with libmagic 5.38 the detected mime type is text/plain

Here's a sample snippet to reproduce the issue

import io, magic
buff = io.BytesIO()
buff.write(b'000000000000000000000')
buff.seek(0)
magic.from_buffer(buff.read(), mime=True)

python-magic is a wrapper around the underlying libmagic implementation. libmagic often changes detection rules to fix bugs etc.
