- Unzip shared string table to system temporary file when large inner XML, reduce memory usage about 70%
- Remove unnecessary exported variable `XMLHeader`, we can using `encoding/xml` package's `xml.Header` instead of it
- Using constant instead of inline text for default XML path
- Rename exported option field `WorksheetUnzipMemLimit` to `UnzipXMLSizeLimit`
- Unit test and documentation updated
- Close spreadsheet and row's iterator required
- New options `WorksheetUnzipMemLimit` have been added
- Improve streaming reading performance, memory usage decrease about 93.7%
- Make variable name more semantic
- Reduce cyclomatic complexities for the formula calculate function
- Support specified unzip size limit on open file options, avoid zip bombs vulnerability attack
- Typo fix for documentation and error message
According to issue #409
There is absolutely no reason for the timezone to be in UTC, and converting the local times to UTC while keeping values is hacky at least.
Excel has no understanding of timezones, hence the user of this library should know what timezone their values are supposed to be, by following the timezone within their timeTime structs.
* extend cell value load to support custom datetime format

* fix numeric values conversion as done in legacy Excel
* fix tests coverage
* revert temporary package name fix
* remove personal info from test XLSX files
* remove unused dependencies
* update format conversion in parseTime
* new UT to increase code coverage
* Resolve code review issue for PR #703
* Rename broken file name generated by unit test

* Allow access to more formula attributes in SetCellFormula
Make SetCellFormula variadic to not break API.
The new arguments are option arguments in which the type of
the formula and the ref attribute may be set.
These need to be set for an array formula to work.
* Add TestWriteArrayFormula to test optional parameters of SetCellFormula
TestWriteArrayFormula writes a document to the test directory that
contains array formulas that are used to calculate standard deviations.
The file also contains values calculated by the Go testcase, so the
results can be verified. It should be tested, if the array formula
works (i.e. shows a number, not an error) and that the values calculated
by the formula and those calculated by Go are the same.
Instead of re-encoding the full sheet to change the namespaces
in the encoded bytes, read the sheet again and do the byte
replacements there.
In this case, file access ends up being more performant than
marshaling the sheet back to XML.
In the SharedStrings test, ensure the strings are actually read.
