v0.7.0

• omx-drive: hfRolloff is the contract's roll-off id (off, 12 kHz, 16 kHz), regenerated against omx-contract 2.11.0 (omx-dsp#97)
• Widen the omx-contract range to >= 2.11.0, < 2.12 (omx-dsp#97)
• README: the drive's oversampling and the gate's key filter rows, generated
• omx keyed-gate: key high-pass and low-pass; omx strip fixes them off
• omx drive: the oversample control, bound to the instance face
• Build against omx-dsp 0.18: floor 0.18.0, ceiling below 0.19
• Drop the pin file; tools/deps-check.sh holds the packaging ranges
• tools: read omx-contract from the installed package, in the spec's range
• Makefile: take the omx-dsp and omx-contract ranges from the spec
• packaging: omx-dsp >= 0.17.0, < 0.18 and omx-contract >= 2.10.1, < 2.11
• omx transient: a thread the arms oracle cannot start is a failed arm, never joined (#36)
• private-refs-check: catch docs/design and harness paths, and fail when git grep fails
• omx transient: the arms oracle names no private source, only what it tests (#36)
• omx deesser: its declaration in the schema's key order, meters after portHints
• gen: the plugin Makefiles' OMXDSP_MIN follows the omx-dsp pin, 0.15.0
• Release 0.7.0: omx-dsp 0.15.0, and manuals from the contract; version and changelogs
• ci: fail on pointers into private repositories, issues, branches and paths
• Public sources state the facts, not pointers into private specs, issues and paths
• test: a travel moved in omx-contract moves the manuals (#104)
• declarations: the manuals read their ranges and defaults from the parameters (#104)
• gen: fill a manual's range, default and limits from its parameters (#104)
• omx transient: the engine's transient arms as an oracle on both faces at the nine RME rates (#36)
• gen: a declaration's oracles are built and run on both faces in make test (#36)
• docs: a declaration names the oracles moved with its effect from the engine (#36)
