Description
**Is your feature request related to a problem? Please describe.**
At present, C++ Reader already supports the filter push-down feature, considering the ease of use, we can also add this feature for high-level APIs
**Describe the solution you'd like**
Pass `FilterOptions` parameters to `ConstructVerticesCollection` and `ConstructEdgesCollection` to specify row pushdown and column pushdown conditions
**Additional context**

Contributor guide
Research direction
Inspect the definitions and call sites of ConstructVerticesCollection and ConstructEdgesCollection, then compare them with the existing C++ Reader filter push-down implementation. Review related issue #98 for context. Done means both high-level APIs accept FilterOptions and support the requested row and column pushdown conditions.
