I've optimized some things in libtasn1 but the times were so bad that
are insignificant. 50% of the time is spent on decoding (I guess that
is expected as a large tree, is a large tree), and the other 50% on
reading the individual values. My change gave a speedup on the
decoding part by caching some values and drops it to 30% of the total

However, to get further improvements an API change is required, i.e.,
an iterator based function to read values for large sequences or sets
that are read in a serialized way.
