Limiting effLevel expansion
1e_inputs expands all effLevels to the largest used effLevel in data
Option clear = tmp; // Find the largest effLevel used in the data
tmp = smax(effLevelGroupUnit(effLevel, effSelector, unit), ord(effLevel));
// Expand the effLevelGroupUnit when possible, abort if impossible
loop(effLevel${ord(effLevel)<=tmp}, ...
This should be moved to 3a and done only if effLevels are actually used in the initFile
