* Minor Fix for AND/OR/XOR
These 3 fall into the set of functions where Excel treats string literals differently depending on whether they are passed to the function directly or as a cell reference. PhpSpreadsheet is updated to try to duplicate that logic. New tests are added. Some existing test results had to change as a result of this code change.
* Adopt A Suggestion From Mark Baker
Reduce if statements by adding functions.
* Fix Unintential Deprecated Calls in Tests - LOGICAL
I think it's best to install these before PR #3166. There are no changes to source code, only to doc-blocks and to test members which continue to inadvertently use calls to deprecated functions.
* Change Unit Tests to Run in Spreadsheet Context
They had been run as direct calls, which is not how most users would use them. Making this change exposed some minor coding errors - SWITCH needs to flatten its arguments, and IFERROR and IFNA were not handling a null testValue in the same manner as Excel.
* Merge branch 'master' of C:\Projects\PHPOffice\PHPSpreadsheet\develop with conflicts.
* New statistical tests
* Sniffs
* Additional statistical function unit tests
