When appending data to an existing sheet, it was possible to get cells in error when reading (DIV/0 for instance). When trying to write them back, `addRow` would throw because `Cell`s in error were not supported by the writers.
This PR adds support for cell alignment for XLSX and ODS files.
You can now align the content of the cells this way:
```
use Box\Spout\Common\Entity\Style\CellAlignment;
use Box\Spout\Writer\Common\Creator\Style\StyleBuilder;
$style = (new StyleBuilder())
->setCellAlignment(CellAlignment::RIGHT)
->build();
...
```
Possible cell alignments are: LEFT, RIGHT, CENTER and JUSTIFY.
Fixes#682
When calling `Row::setCellIndex`, it's possible to create a Row with holes.
Instead of iterating over existing cells of a Row, we should instead use the cell indexes (from 0 to max cell index).
From PHP 7.4, the recommended way to disable the escape character for fgetcsv() and fputcsv() is an empty string, instead of "\0".

Whether the spreadsheet is using 1904 dates or not is controlled by a XML property. Its value can be the string "false" that is not mapped to the boolean "false" but to the boolean "true"... Therefore Spout was previously using the wrong date system when this property was set.
Removed the `ReaderEntityFactory::createReader(Type)` method and replaced it by 3 methods:
- `ReaderEntityFactory::createCSVReader()`
- `ReaderEntityFactory::createXLSXReader()`
- `ReaderEntityFactory::createODSReader()`
This has the advantage of enabling autocomplete in the IDE, as the return type is no longer the interface but the concrete type. Since readers may expose different options, this is pretty useful.
Similarly, removed the `WriterEntityFactory::createWriter(Type)` method and replaced it by 3 methods:
- `WriterEntityFactory::createCSVWriter()`
- `WriterEntityFactory::createXLSXWriter()`
- `WriterEntityFactory::createODSWriter()`
Since this is a breaking change, I also updated the Upgrade guide.
Finally, the doc is up to date too.
Add `WriterEntityFactory::createWriterFromFile`, working like `ReaderEntityFactory::createReaderFromFile` (guessing writer type from file name).
Use static functions when needed.
