Function to calculate the drawdown using the Cooper-Jacob solution for a confined aquifer

1	cooper_jacob_solution(ptest, a, t0, t)

`ptest`	A pumping_test object
`a`	Slope of the straight line fitted to the drawdown data using the Cooper-Jacob approach
`t0`	Intercept of the straight line fitted to the drawdown data using the Cooper-Jacob approach
`t`	Numeric vector with the values of time

This function returns a numeric vector with the calculated drawdown
