module: calculate UVA light intensity correctly for rset != RSET_240K

Browse Source 
- compensation for rset != RSET_240K was wrong, it increased UVA power/ADC step for rset > RSET_240K
- UVA power/ADC step should have been decreasing as refresh time (sampling time) got longer
- same behavior as with integration_time setting, that works correctly
