Patch release: item-source readers guard the array test and accept ROneCOne sequences. Closes #1.
ItemsFrom, ChosenFrom, and CheckedFrom reached a bare IsArray(source) on any source that was not a Range or Collection. IsArray on a ROneCOne dereferences its default member and raises, which the pump swallowed while leaving Err dirty, and a ROneCOne sequence yielded no items at all. The three readers now share one IsObject-guarded helper, so IsArray appears exactly once in the runtime and never receives an object. That helper also accepts a ROneCOne sequence, so a picker can be fed straight from a ListOf, a Queryable result, or a Json.Deserialize array.
Requires ROneCOne 1.8.1 or later. Demo workbooks attached, macros enabled. Full detail in CHANGELOG.md.
