Work with yearly NDep values per plot
Max Possch has delivered yearly NDep values for each plot, spanning the period 1880-2020. See: w:\projECTS\DOREN22\b_prepareddata\EMEP_averaged\max_20230515\
We need a new function in src\preparation\header_management_functions.py that can take these data and performs a summary statistic for each plot. Eg. for plot X (surveyed in 2010), calculate the summed NDep over the period 2000-2010.
