Function to calculate the drawdown using a general_radial_flow solution

1	general_radial_flow_solution(ptest, a, t0, n, 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
`n`	Flow dimension
`t`	Numeric vector with time

A numeric vector with the calculated drawdown
