Shomiti Surveyor 3.x appears to have changed the version number in the

file header to 4; fortunately, as they appear to put their extensions to
snoop into the padding at the end of the record, all their capture files
look alike to programs such as snoop and Ethereal that ignore the
padding, so we can just treat version 4 just like version 2 (unless and
until Brent decides a new snoop format is called for, changes the record
header, and picks a version number that's the same as one used by
Shomiti).
