Error in documentation scipy.special.modstruve

[ashwinxsingh]

The documentation for the scipy.special.modstruve function says that modstruve is defined as -iexp(-i\nu\pi/2)H_\nu(z) when it should be iexp(-i\nu\pi/2)H_\nu(iz). Without the iz in the argument of the struve function, the modified struve function becomes complex for real inputs and this is not consistent with the output of scipy.special.modstruve, nor the definition cited in https://dlmf.nist.gov/11.2. This is a quick fix, literally just change the z to an iz in the argument of H in the docstring only, not the actual function.
