erts: Adjust term_to_binary reduction factorsR16B02_yielding_binary_to_term
Made them powers of 2 for faster calculations. 500 encoded terms per reductions seemed a bit much, lowered to 32. TERM_TO_BINARY_SIZE_FACTOR was not used in practice as it was only applied to small binaries. Lowered from 500kb to 256kb compressed bytes per trap call.
