Creates a new GMimeFilterBest filter. flags are used to determine
which information to keep statistics of. If the
#GMIME_FILTER_BEST_CHARSET bit is set, the filter will be able to
compute the best charset for encoding the stream of data
filtered. If the #GMIME_FILTER_BEST_ENCODING bit is set, the filter
will be able to compute the best Content-Transfer-Encoding for use
with the stream being filtered.
