Added

• isAddress() and isRange() check that an address exists: rangeArray() parses a syntax and says nothing about the borders of a sheet, these two do
• escapeString() encodes control characters with its second argument, so a text becomes a complete ST_Xstring. CR is encoded, TAB and LF are left as they are
• PHP 8.5 is supported officially, the tests run on PHP 7.4, 8.0, 8.1, 8.2, 8.3, 8.4 and 8.5 (ubuntu and windows)

Fixed

• colLetterRange() returned an empty array for an address containing a zero digit: 'B10:E20' and '10:30'
• inRange() did not accept a single cell as a range: inRange('B2', 'B2') gave a warning and false
• rgbToHsl() did not accept AARRGGBB, while xlsx keeps colors in ARGB, and it produced warnings on an unparseable color
• shiftAddress() built a broken address such as '-4' when a cell was shifted out of a sheet, addToRange() did the same for a relative range
• addToRange($cell, $range, true) returned an array where range, range_abs and *_cell_abs described the range before it was extended, while max_cell described it after
• colNumber() returned the number of the real column XFD for a column out of a sheet: 'XFE' and 'ZZZ' gave 16384
• correctColor($color, 0) returned a neighbour color instead of the given one, 6 of 12 checked colors were shifted
• an input that cannot be parsed produced a warning or a TypeError in A1toRC(), RCtoA1(), shiftAddress(), shiftAddressRC(), addToRange() and inRange(), a neutral result is returned now
• the cache of colNumber() grew without a limit, taking about 6 MB per 200000 calls while reading a sheet cell by cell

Changed

Worth a look while upgrading, these results are different now:

The palette of Excel cannot be reproduced exactly by any documented algorithm: the base of 240 and of 255, quantized HLS and a literal port of the integer Win32 RGBToHLS were compared on 14 colors of the Office theme, the best result is 9 of 14 and every miss is one unit in a channel. A color kept by a zero tint is taken as the criterion instead.
