Version 1.6.0

• New build system based on cmake. Refer to README.md for new installation instructions.
• FANS/1-A CPDLC, ADS-C and ACARS decoders have been removed. These features have been moved to libacars library, which is now a mandatory dependency (compilation will fail if libacars is not installed). Refer to README.md for details.
• Added support for SoapySDR library (contributed by Fabrice Crohas). However there are still some limitations with respect to SDR types which dumpvdl2 can work with. As of now, the device must support a sampling rate of 2100000 samples per second. This will be addressed in a future release.
• The program should now compile and run on MacOS, however this hasn't been tested well. Feedback and bug reports are welcome.
• Minor bugfixes
