🎨 Allow type_bitset construction with generic type list

elbeno · elbeno · commit 69bdef5a86fb · 2026-02-03T18:29:20.000-07:00
Problem:
- `type_bitset` expects a `stdx::type_list` to be passed to the constructor; in
  fact any "type list" (like tuple) could work.

Solution:
- Genericize the `type_bitset` constructor.
