Expand Chart Support for schemeClr and prstClr (#2879) 

* Expand Chart Support for schemeClr and prstClr

Fix #2219. Address some, but not all, issues mentioned in #2863.

For Pie Charts, fill color is stored in XML as part of dPt node, which had been ignored by Reader/Xlsx/Chart. Add support for it, including when specified as schemeClr or prstClr rather than srgbClr. Add support for prstClr in other cases where schemeClr is supported.

* Update Change Log

Add this PR.
