- mix.exs: @version 0.16.0 -> 0.17.0
- lib/statifier_blocks/compiler.ex: @compiler_version to match
- README.md: install pin ~> 0.16 -> ~> 0.17
- CHANGELOG.md: assembles the 0.17.0 section from six fragments
- changelog.d/: the six promoted fragments deleted

A minor and not a patch: sb-4r1p removed
`StatifierBlocks.Core.Duration.to_iso/1` and `predicator?/1` and
reshaped `to_delay/1` and `DurationInput.read/1`, so the published
surface is smaller than 0.16.0's.

Cut, not published: the tag, the GitHub release and the Hex publish are
the operator's. Dependency requirements are byte-identical to main's,
and `mix hex.build` accepts the package at this version.
