Charts still need some work, but they are now in good enough shape that the code that reads them can handle namespacing properly. Rather than a set of static routines, Reader/Xlsx/Chart needs to be changed to a regular object, with the relevant namespaces passed in the constructor. I am still looking for a test spreadsheet with non-standard namespacing for a full-blown test, but, in the meantime, the existing tests and samples will suffice. When I find a test case, I will certainly add it. The resulting code is actually simpler than it had been because of the elimination of the need for a NamespacesMeta variable in all the function signatures. Because of that, enough errors disappeared from Phpstan that I decided to just finish that job - its baseline file now dips below 5,000 lines.

I think we need some Change Log updates with all these fixes and improvements that you've been implementing for Charts. That original code was written over a long weekend (without access to the documentation), and has barely been touched since, so it wa in real need of the TLC that you've provided |

Wait - there's documentation??? :-) I will update the Change Log as a further commit to this PR some time today or tomorrow. |
Need to document many chart changes.

Continuing the work from PHPOffice#2828, PHPOffice#2841, PHPOffice#2846, and PHPOffice#2852. This is probably my last change in this area for a while. Bubble charts can have bubbles of different sizes. Phpspreadsheet had not supported this. Openpyxl comes with sample code to generate such a chart. I was especially drawn to that solution because its namespace usage would have been unexpected before 2852. And it turned out to come with other surprises - use of absolute paths in the .rels files (PhpSpreadsheet expected only relative), use of a one-cell anchor to place the chart (PhpSpreadsheet expected two-cell anchor or absolute positioning), plaintext in the legend (Phpspreadsheet expected RichText), no cached values for chart data. Excel handles the file okay, and this PR makes sure PhpSpreadsheet does as well. This file is now Samples/Templates/32readwriteBubbleChart2, and is used for both generating a sample output file and in formal tests. A new sample in the 33* series demonstrates how to code these.
