`feat`: implement `Simplicial` with canonical orientations

[FiberedSkies]

Description

Implement a Simplicial variant of the current general cell complex implementation using Cell and Skeleton with canonical orientations. Canonical orientation over a simplicial being defined as $[b:a] = (-1)^n$ if you have to remove the $n$-th vertex of $b$ to get back $a$, and $[b:a] = 0$ if $a$ is not a face of $b$.

Details

• implement Simplicial as a specific Skeleton of $n$ dimensions with 0-cells (vertices), 1-cells (edges), 2-cells (2-simplex/triangles), etc. must function for up to an arbitrary $n$ dimensions.
• implement a builder pattern for a CellularSheaf with canonical orientations as described above and initialized restrictions from a Simplicial
