It is sometimes desirable to offer an alias for an argument, but without it
appearing it in the usage. For example, to phase out a deprecated wording of
an argument while not breaking backwards compatible. This can be done with
the ``ArgumentParser::add_hidden_alias_for()` method.
```cpp
argparse::ArgumentParser program("test");
auto &arg = program.add_argument("--suppress").flag();
program.add_hidden_alias_for(arg, "--supress"); // old misspelled alias
```
