feat: Add parallel iterators

[kdy1]

Description:

I introduced swc_par_iter, which uses swc_parallel for join operations. It's not perfect, but this PR looks like a good starting point. I decided to implement it in a separate crate than chili because I need the ability to switch parallelization library.
