#676 Rule alignment fixes for non compliant platforms / Fix for emscripten demo

This is a fix for #584, but the PR scope may be potentially larger : without this fix, the handling of compiled rules is not guaranteed to be compliant across platforms, since casting to int* may happen on non aligned char* , which has to be avoided.

Some minor options also have to be added to the emscripten compilation workflow to make it work again with newer versions.
