This is behind a feature flag as it makes the interface harder to use and 'forces' an additional non-standard crate. But it looks like it's worth it in some cases especially for tape parsing.

[Licenser]

the 0.26% decrease in coverage is probably based on property-based variation, so in acceptable limits
