See #1285, which went stale and was closed, but recently received some positive feeback. It seems easy to implement, and the only other plaintext file format, Html, allows loading from a string. Those two reasons combined suggest that we should do it.
Drawings in an Xlsx file are stored in such a way that Php can read their contents using the `zip:` protocol. This does not, however, work when the file is read by PhpSpreadsheet and then saved as Html or Pdf, since the browser will not recognize that protocol even if the file is available. Such drawings need to be saved in the html as embedded images in order for the copy to display them properly. This is true even when the writer is set to not embed images (default).
An additional problem arises when an Html file with an embedded image is read, because `Worksheet\Drawing::setPath` attempts to validate the path, which it cannot do for the `data:image` Url which embedded images use.
And yet another problem. Writer/Html writes out a MemoryDrawing as a png using the imagepng function; but then declares it as jpeg in the Html. This is now corrected.
And a fourth problem. Writer/Html ignores the last row if it contains nothing but a Memory Drawing, which can be true when copying an Xls file.
These changes are testable (it's how I discovered the second part of this parlay). I think it is also useful to add a sample to see the results of this type of copy.
* Real Errors Identified in Calculation by Scrutinizer
Before Scrutinizer broke, I took a look at the remaining 43 errors which it categorized as 'major'. Most of these were false positives, but, in the case of Calculation and Reader/Xlsx/Chart, I was able to determine that its analysis of some of the problems was correct. There is little point addressing the false positives until it starts working again, but we should fix the real errors.
This PR addresses the real errors in Calculation.
- A test for `$pCellParent` should have been a test for `$pCellWorksheet`.
- A test for `$operand1Data['reference']` should have been a test for `$operand1Data['value']`.
- A test for `$operand2Data['reference']` should have been a test for `$operand2Data['value']`.
* Fix Attempt to Erroneously Call trim on Array
Fix#2780. Warning message is being issued when getting calculated value of cell with value `=INDIRECT(ADDRESS(ROW(),COLUMN()-2))/$C$4`. This appears to be the case for all recent (and probably not so recent) releases; it is not a result of changes to the code base. Fix added to this PR because the erring section of code was proximate to code already changed in the PR. Test added.
* Minor Code Changes
Apply some suggestions from @MarkBaker
PHP 8.2 is supposed to deprecate the use of `['self', 'functionname']` for callables, suggesting the use of `[self::class, 'functionname']` instead. We made this change in a recent PR, and, while I'm thinking about it, I'll fix the remaining 2 modules with this construction. Vlookup is already adequately covered in unit tests. Reader/Xls/MD5 is not; a unit test is added.

- An assignment to `$XaxisLable` should be an assignment to `$XaxisLabel`.
- An assignment to `$YaxisLable` should be an assignment to `$YaxisLabel`.
Fixed that bug, using a slightly faster algorithm for the sort index than the simple fix would have used, and modified the tests that didn't have the correct expected result :-(
