Drift corrects raw data from the EA based on standards

Description

This function uses repeated analysis of known standard to check for an, if desired, correct raw data for instrumental drift. The function first test for sufficient data to make the correction. If data are insufficient, the raw data ar copied unchanged to new column, .csv written, and outcome printed to the console. If the data are sufficient, a drift analysis is done and plots generated. The user is asked if they want to drift correct the C data, N data, or both. The function returns a character vector that indicates the results of the drift correct as N, C, both, or none.
