Successor to PR #3523. There are 494 single-line changes (`public function provider` to `public static function provider`) in this PR. None of these were made manually; they were all created with the following script (adapted from
https://stackoverflow.com/questions/25909820/how-to-recursively-iterate-through-files-in-php):
```php
$dir = 'C:/git/unit10prep2/tests/PhpSpreadsheetTests';
$it = new RecursiveDirectoryIterator($dir);
// Loop through files
foreach(new RecursiveIteratorIterator($it) as $file) {
if ($file->getExtension() === 'php') {
$contents = file_get_contents($file);
$new = preg_replace('/public function (\\w*)([Pp])rovider/', 'public static function $1$2rovider', $contents);
if ($new !== $contents) {
echo "changing $file\n";
file_put_contents($file, $new);
}
}
}
```
After this PR, there will be one more, with a small number of test changes, and enabling PhpUnit 10 for Php 8.1+.
* Coerce Bool to Int for Unary Operation on Arrays
Fix#3389. It seems some functionality was left behind when JAMA was eliminated (PR #3260). In particular, it is apparently a known trick to use double negation on boolean values as arguments to functions like SUMPRODUCT.
* Fix 3396
Treat booleans in arrays as int for mathematical operators as well.
* Edge Case
When array operand was neither numeric nor boolean, PhpSpreadsheet had always been evaluating the operand as #NUM!. It will now propagate an error string like #DIV/0!, and treat non-error strings as #VALUE!, consistent with Excel.
* Fix Unintential Deprecated Calls in Tests - LOOKUPREF
I think it's best to install these before PR #3166. There are no changes to source code, only to test members which continue to inadvertently use calls to deprecated functions.
* Fix deprecation DocBlocks
Deprecated->deprecated, adjust see and comments
* One Intentional Deprecation
Annotate it.
* Start work on array-enabling the Lookup and Reference functions
Requires a new method (`evaluateArrayArgumentsSubsetFrom()`) in the `ArrayEnabled` Trait to handle functions where the arguments that need special array handling are trailing rather than leading arguments
