Fixing shared build on static demand problem by temporary switching off BUILD_SHARED_LIBS in CMake configuration.

Switching to default dynamic lib build mode by changing base definition behavior. If you do not define anything, you will end up with a shared library, now.

Merge branch 'feature/sweetspot_widening' of https://git.rwth-aachen.de/ita/ITACTC into feature/sweetspot_widening

Adding CMake configuration switch to export HRIR and CTC filter sets to harddrive as multi-channel WAV files (default: off)

Removing factor sweet spot widening and adding factor crosstalk cancellation and wave incidence angle comp with setter/getter

Moving room compensation code to branch feature/room_compensation (Erik's code). This master branch is now back to initial state.

adding a new feature to set a desired delay for each channel individually (affecting the two convolvers per N-CTC channel), i.e. to account for delay differences within loudspeakers. Still, the setter for a single delay is available and overwrites all individual values, if used.
