deco: _really_ make sure the deco state is fully initialized
I incorrectly thought that 'ci_pointing_to_guiding_tissue' was the only
missing initialization, because that is the only one valgrind pointed at.
... that is, until I started looking at a few more dives, which showed
that there were other parts tht weren't initialized either, like
double tolerated_by_tissue[16];
double tissue_inertgas_saturation[16];
double crushing_onset_tension[16]; // total inert gas tension in the t* moment
so just make sure to clear the whole data structure, to avoid any random
behavior due to uninitialized deco state.
