Nim wrappers for PB C++ code

We start with pbbbam, of course.

To install pbbam

We use pkg-config, so do something like this:

PREFIX=$(pwd)/.git/PREFIX
meson --prefix=$PREFIX --buildtype=debug build
cd build
ninja -j2 install

export DYLD_LIBRARY_PATH=$PREFIX/lib
export PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig

Example

make dataset.exe
