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.
All entities will now be created through a single factory (including the Writers).
Also, added a EntityFactory::createRowFromArray() to make it easier to create rows
This commit introduces Row and Cell entities, that will replace the arrays passed in previously.
It also adds support for Cell styling (instead of Row styling only).
Added ODS writer
Refactored XLSX writer to abstract some pieces into an abstract multi-sheets writer
Created an abstract style helper
Moved shared components around
Invalid names can also be triggered by:
- character ":"
- single quote at the beginning of the name
- single quote at the end of the name
Introduced a StringHelper, wrapping multibyte strings functions
Based on Excel requirements:
- it should not be blank
- it should not exceed 31 characters
- it should not contain these characters: \ / ? * [ or ]
- it should be unique
