* Fix reading of files in the root of a zip
Xlsx.php relies in dirname($filename) for path generation. When path is a bare filename (i.e. files in the root of the zip file), dirname($filename) returns a relative path to the current directory ("."). This is ok for filesystems, but not when accesing contents in a zip file.
Xlsx documents with files in the root of the zip container are not common, but legit. I've found it to happen in files generated by Google Campaign Manager 360.

It gets awkward when the defined name is for an actual range rather than for an individual named cell; because we need to manipulate the stack when that happens.
The code is ugly, and this is a rather simplistic approach, but it works as long as the named range is a cell, a cell range, or even a "chained" range - it won't work if we have union or intersection operators in the defined range - but it does provide formula support that never existed before.
Current implementation for all methods that take a single cell reference argument:
- `setCellValue()`
- `setCellValueExplicit()`
- `getCell()`
- `cellExists()`
- `setBreak()`
- `freezePane()`
- `getComment()`
Also introducing a CellRange object to work with similar cases for methods that accept a cell range rather than simply a cell address; and RowRange/ColumnRange objects for those cases.
Still need to apply to methods that accept a cell range or single cell:
- `mergeCells()`
- `unmergeCells()`
- `protectCells()`
- `unprotectCells()`
- `setAutoFilter()`
Then there's a few special cases that accept row and column ranges, not simply cell ranges; or a series of cell ranges.
The code could stil do with some cleaning up, and better optimisation for memory usage; but all tests are passing... that's for full multi-level sorting (including direction), and allowing for correct sorting of sting/numeric datatypes.
- Update existing ranges, expanding if necessary, rather than trying to clone for each individual cell
- Update conditions, so that cell references and formulae are maintained correctly
Note that absolute as well as relative cell references should be updated in conditions
And a bugfix when deleting cells that contain hyperlinks (the hperlinks weren't being deleted, so were being "inherited" by whatever cell moved to that address)
* Add two cell anhor drawing.
* Add "Support for two cell anchor drawing of images." to CHANGELOG.md
* Add pull-request link to "Support for two cell anchor drawing of images." of CHANGELOG.md
* Split Information functions into a dedicated class and namespace and categorise as Value or Error
* Refactor all error functions into the new ExcelError class
