Add a Cmake build

[moonwatcher]

This PR adds the ability to build pheniqs with CMake. It also allows to fetch and build the dependencies into the executable if they are not present on the host. A corresponding markdown instruction file is also added.

rm -rf build; mkdir build
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release;
cmake --build build -j$(nproc)

To force fetching dependencies

rm -rf build; mkdir build
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release \
      -DVENDOR_ZLIB=ON \
      -DVENDOR_BZIP2=ON \
      -DVENDOR_LZMA=ON \
      -DVENDOR_HTSLIB=ON \
      -DBUILD_STATIC=ON
cmake --build build -j$(nproc)
