Subject: [PATCH] Fix copy constructor member access in VectorHashBiTable

The copy constructor of VectorHashBiTable was incorrectly accessing

`table.s_` instead of `table.selector_`, causing a compilation error

with stricter C++ compilers.

This issue manifests with GCC 15, which enforces more rigorous checks

on template member access. The compiler error was:

  error: 'const class fst::VectorHashBiTable<...>' has no member

  named 's_'; did you mean 'h_'?

The member variable is actually named `selector_`, not `s_`. This fix

aligns the copy constructor with the correct member variable name used

throughout the class definition.

Fixes build failures on systems with GCC 15.
