[Experiment] Nanobind

[ax3l]

What would it take to migrate to nanobind?

Pro's

See advertising, all great :)

Love the

• speed & size
• separate headers for features
• non-header-only approach
• C++17 and newer only
• faster builds: no LTO needed anymore

Notes / Con's

• limited official compiler support (Clang, GCC, MSVC), especially no coverage yet for GPU (Nvidia NVCC & NVHPC, AMD ROCm, Intel OneAPI)
• still many warnings (e.g., Wshadow, Wpedantic) in base lib
• ~currently, limited public docs~ improved :)
