Feature parity between GoLang and C

[ashvardanian]

Our GoLang binding for USearch is missing several APIs that are available in the C version. Let's add these to make the GoLang version just as powerful!

Missing APIs:

1. SerializedLength: Get file size after serialization.
2. SaveBuffer: Save index to an in-memory buffer.
3. LoadBuffer: Load index from an in-memory buffer.
4. ViewBuffer: View index from an in-memory buffer without copying.
5. Metadata: Load index metadata from a file.
6. MetadataBuffer: Load index metadata from a buffer.
7. ExpansionAdd: Get expansion value for index creation.
8. ExpansionSearch: Get expansion value for search.
9. ChangeExpansionAdd: Set new expansion value for index creation.
10. ChangeExpansionSearch: Set new expansion value for search.
11. HardwareAcceleration: Get SIMD capabilities.
12. MemoryUsage: Get memory usage of the index.
13. Distance: Compute distance between two vectors.
14. ExactSearch: Multi-threaded exact nearest neighbors search.
15. Rename: Rename a vector to a different key.
