Summary description: Flexible cross-references with contextual checks based on zref

Announcement text:
----------------------------------------------------------------------

## v0.2.1 (2021-09-16)

### Changed
- Use `msg_line_context:` instead of `msg_line_number:` for messages.
- Use more efficient way to set checks as option keys in `zcheck`.
- Spare setting end label in `zcheck` for checks which don't need it.
- Separate `zref` property lists for checks and targets, so that only
the minimum set of required properties for each are used.

### Added
- New `pagegap` check.
- Provide infrastructure for integration with `zref-clever`.
