Fixed getting the wrong celltype for cached celltypes, when result is a
string, by saving the formula type as a boolean flag in the
StreamingCell and handling formula strings("t=str") as a normal string.

Sorry it's taken me so long to review this, I had kind of a crazy summer and haven't had any time for my GitHub projects (or much of anything else, really). Would it be alright if this change waited until the update to POI 4.0.0 goes through? It looks like @pjfanning already has applied this to his fork post-upgrade, so merging it now would cause a few merge conflicts. |

@monitorjbl this is not mixed in with my pull request to your project - I have a fork of my own that I'm maintaining independently (for now) - so it's safe for you to merge this |

Thanks a lot for merging. This was a major blocker for us! |

The celltype
strused to be handled as if it has the celltypeCellType.FORMULA. Even if it only occurs as a result of a formula, it should still be handled as a string.This bug is fixed by using a boolean flag in the
StreamingCell.java, that is true when the element is found in the excel file.Using the method
getCellTypeEnum()now returnsCellType.STRINGforstras well. It now also checks if the the cell has the formulaType and will returnCellType.FORMULAif the boolean flag is true.The method
getCachedFormulaResultTypeEnum()will only return a cellType if the boolean flag is true and will also return CellType.String forstr.Included is a unittest covering the bug.
Let me know if you need any more information, of if I should change something in the code.
