It is useful to support different versions of tshark which may have
updated disectors. In that case, there may be no filter that works with
all version of tshark.
Permit passing multiple filters which will be tried in-order. This
allows first trying the filter for the newer version and then falling
back to an older filter in order to support different tshark versions.
