Allow HTML Reader to load from string
We often want to export a table as an excel sheet. The system renders the

a reader

Branch pruning around IF function calls to avoid resolution of every branches
Calculation engine was resolving every function by first resolving its arguments
including IFs, this was causing significant over evaluation when IFs were used
as it meant for every case to be evaluated.

Introduce elements to identify ifs and enable better branch resolution
(pruning). We tag parsed tokens to associate a branch identifier to them.

Fix for worksheet lookup for worksheets with spaces in the title
Sheet titles containing " " or "!" will be quoted in formulas. This commit

name will be lost when reading the workbook from file.

Fix infinite loop when reading invalid ODS files
According to the spec, http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part1.html#__RefHeading__1415588_253892949,
a `<table:table-row>` can only ever contains a `<table:table-cell>` or
a `<table:covered-table-cell>`, but it seems that some invalid files in the wild
may contains something else. That would trigger an infinite loop. So instead we
totally ignore the invalid content.

Remove duplicate strtoupper
Removing the duplicate strtoupper call has a meaningful impact on
performance since this method is called at least once per cell.

`Worksheet::getCells` currently calls `strtoupper` twice. `strtoupper`
is kind of expensive and this method is called at least once for every
cell in the spreadsheet.  By removing the unnecessary second call the
runtime decreases by 18% when importing a ~100K cell spreadsheet.

Dennis Birkholz 95c41da020 Cache readFilter access and skip inner loops for empty/default readFilter (#773)
For large XLSX files `Reader/Xlsx::readColumnsAndRowsAttributes()` performs
a lot of calls to `$this->getReadFilter()` and `$this->getReadFilter()->readCell()`
as `readCell()` is called twice for each (possibbly filled) cell.

By ignoring calls to the DefaultReadFilter implementation (which always returns true),
using no custom read filter will not incur any runtime penalty.

The runtime penaltiy when using a custom read filter is reduced by a third by
caching the read filter into a variable instead of using the getter method.

Fixes issue #772.

Write generated HTML into Mpdf in chunks, rather than as one gigantic string
Due to a limitation in Mpdf, the HTML string passed to its WriteHTML method
must not exceed a particular length. PhpSpreadsheet produces one HTML string
containing all spreadsheet data when writing to HTML, which can easily exceed
Mpdf's size limit. Thus, it was impossible to write large spreadsheets to PDF
using the Mpdf writer - this change fixes that issue.

Timur 50a9bc83ab Sheet title can contain exclamation mark (in formulas)
When extracting sheet title from string reference (like `"Work!sheet1!A1"`), PHP function `explode()` divide this string into three parts: `['Work', 'sheet1', 'A1']`. And then these wrong values are used in formulas, ranges, etc.

This change fix that problem by using special function `Worksheet::extractSheetTitle()`. This function also has been changed to make sure that worksheet title can contain "!" character. So, that function search last position of "!" in reference string and divide it to 2 parts correctly: `['Work!sheet1', 'A1']`.

Derek Bonner 01501b6ff2 Remove locale from format string to prevent formatting error (#644)
When a formatting string has a locale in it an error can occur when outputting. For example when the format string with a locale such as `[$-1010409]#,##0.00;-#,##0.00` appears, a value of 9.98 comes back as $9.98. This is because at https://github.com/PHPOffice/PhpSpreadsheet/blob/1.4.0/src/PhpSpreadsheet/Style/NumberFormat.php#L711 the numberFormat regex will match to the zeros inside the locale ([$-1010409]). Attempts to adjust the numberFormat regex caused regressions in other tests. Adding another step to filter out the locale caused no regression.

Avoid memory exhaustion when cloning worksheet with a drawing
When cloning `BaseDrawing`, its worksheet will be set as null and thus be
orphaned. But when cloning the worksheet, it will re-assign itself as the
new worksheet for the BaseDrawing.

That way we avoid recursive cloning of a Worksheet that would clone a
BaseDrawing that would clone a Worksheet etc.
