Update dependencies (#4595)

Use the most recent versions in ConanCenter.

* Due to a bug in Clang 16, you may get a compile error:
  "call to 'async_teardown' is ambiguous"
  * A compiler flag workaround is documented in `BUILD.md`.
* At this time, building this with gcc 13 may require editing some files
  in `.conan/data`
  * A patch to support gcc13 may be added in a later PR.
