* feat: gap-fill API surface parity with nrel-spa JS (v1.0.1) Add formatTime, calcSpa, SpaFormattedResult, SpaFormattedAnglesResult, functionCode parameter for getSpa (spaZa/spaZaInc/spaZaRts/spaAll), incidence field on SpaResult, and export all function code constants. All 48 tests pass including numerical cross-validation against the NREL SPA reference date (Golden CO, 2003-10-17) and surface incidence angle. * docs: add CHANGELOG.md for v1.0.1 release * chore: polish pubspec, fix unused import, add wiki docs
