I would expect that not all of TFM would need to be added, i.e., what is
needed is just couple of more optimized algorithms for modular
multiplication. That should not increase size by 100 kB, but it may take
some effort to find the exact parts from LTM that would need to be
merged into libtommath.c. Based on my notes in libtommath.c, some set of
optimized algorithms increased the size by 15 kB.
