Currently, `derivepassphrase` does not report its “build flags“ or its supported optional features (passphrase derivation schemes, PEP 508 extras, etc.). So callers of `derivepassphrase` need to infer support for optional features through other means, such as trying out the desired feature directly, or observing support indirectly e.g. in the `--help` output.

**Therefore**, `derivepassphrase` should include a way to report its build flags and supported features.

A common way to implement this is to expand the `--version` output to include this information (in a structured tabular format, for machine-parsability).

This was implemented in commit 6741af2eaa6fba39717997292ec25baf5f1f4f20.
