Number of realization-space components

The number of irreducible components of the characteristic-zero realization space, counted over $\overline{\mathbb Q}$. According to scripts/count_components.jl, the saturated characteristic-0 ideal is decomposed into minimal primes, and each prime contributes its number of conjugate, absolutely irreducible components. Free and rigid spaces count as 1. The column is only computed for realizable matroids.

Not to be confused with n_connected_components, which is a property of the matroid itself.
