[fix] in tuple_record: clear() on type that models tuple-like

[swewagner]

I tried to use biocpp-io in a project that requires C++23 and encountered an issue with the tuple_record. It implements the clear() function through std::apply.
Since C++23 std::apply needs the secound argument to be tuple-like (see here).
I think the proposed changes fix this and change nothing else.

Thank you for the PR. It LGTM, however the CI seems to be broken (unrelatedly).

I will see whether I can fix the CI this week. If I don't merge this within the next two weeks, please ping me 😇
