Having a parallel project to complete cover Document Properties, I turned my attention to to Document Security. As happens, this particular change grew a bit over time.
Coverage and Testing Changes:
- Since the Security object has no members which are themselves objects, there is no need for a deep clone. The untested __clone method is removed.
- Almost all of the coverage for the Security Object came about through samples 11 and 41, not through formal tests with assertions. Formal tests have been added.
- All methods now use type-hinting via the function signature rather than doc block.
- Coverage is now 100%.

Bug:
- Xlsx Reader was not evaluating the Lock values correctly. This revelation came as a result of the new tests ...
- Which showed that Xlsx Reader was testing SimpleXmlElement as a boolean rather than the stringified version of that ...
- Which didn't matter all that much because Xlsx Writer was writing the values as 'true' or 'false' rather than '1' or '0', and (bool) 'false' is true.
- Xlsx Reader clearly needed a change. I was trying to avoid that while awaiting the namespacing change. At least this is restricted to a very small self-contained piece of the code.
- It is less clear whether Xlsx Writer should be changed. It is true that Excel itself uses 1/0 when writing; however it is equally true that it recognizes true/false as well as 1/0 when reading. For now, I have left Xlsx Writer alone to limit the change to what is absolutely needed.

Other Changes:
- I was at a complete loss as to what "lock revisions" was supposed to do, and it took a while to find anything on the web that explained it. Thank you, openpyxl, for coming through. I have documented it for PhpSpreadsheet now.

Miscellaneous Note:
- There remains no support for Document Security in Xls Reader or Writer (nor in any of the other readers/writers except Xlsx).
- No Phpstan baseline changes, possibly for the first time in any of my PRs since Phpstan was introduced.
