Added program to generate FFTW wisdom

Use a FFTW wisdom file and use optimal FFT sizes for convolution functions
Parameters through Parset or Input
Write spheroid and average beam image with file name based on image name
Use given mueller masks

Flip done in LofarVisResampler, Multithreaded fix in get in LofarFTMachine
