Feature/c++23 (#76)

* Make separate branch for C++23

* Fix merge errors from develop

* ci: update to clang-18 via pkgx

This should resolve the build failure for updating to C++23. clang-17 didn't support std::expected, but clang-18 should.

* ci: Fix checking twice on PRs and pushes

* ci: Fix Travis and AppVeyor

* ci: Fix clang on Travis-CI

* ci: Don't double build PR pushes on Travis-CI
