v1.0.0

• Stable release on rasuvaeff/schema ^1.0 and rasuvaeff/json-ld ^1.0
  (rasuvaeff/pinned-http-client ^1.0 suggested). The public API and
  behaviour are those of 0.3.0, checked in the cska-one pilot; from here on
  SemVer applies strictly.
• Docs: siteName falls back to providerName whether or not
  hostAsSiteName is on (the 0.3.0 note said otherwise).
