Add sine sweep generation function

Since we have a function to estimate the frequency and impulse response from sine sweep measurements it would be good to create one to generate the sweeps.

Farina’s and Novak’s papers should be a good starting point. Ideally, the user should be able to choose which of the two methods they would like to use to generate the sweep (Farina’s “conventional” or Novak’s “synchronised”).
