Load trophic discrimination factor (TDF) data

Source: R/load_discr_data.R

load_discr_data loads the trophic discrimination factor (TDF) data. TDF is the amount that a consumer's tissue biotracer values are modified (enriched/depleted) after consuming a source. If tracers are conservative, then set TDF = 0 (ex. essential fatty acids, fatty acid profile data, element concentrations).
