Description: Provides an implementation of simplicial complexes for
    Topological Data Analysis (TDA). The package includes functions to
    compute faces, boundary operators, Betti numbers, Euler characteristic,
    and to construct simplicial complexes, including Vietoris-Rips, Cech,
    Alpha, Delaunay, Witness, flood, and (via a Freudenthal triangulation)
    cubical complexes for grid and image data. It also implements persistent
    homology, from building filtrations (via a single build_filtration()
    entry point covering all of the above) to computing persistence
    diagrams, persistence landscapes, and Wasserstein/bottleneck distances
    between diagrams, with the aim of helping readers understand the core
    concepts of computational topology.
    Methods are based on standard references in persistent homology such as
    Zomorodian and Carlsson (2005) <doi:10.1007/s00454-004-1146-y>,
    Chazal and Michel (2021) <doi:10.3389/frai.2021.667963>, and
    Otter, Porter, Tillmann, Grindrod and Harrington (2017)
