* Commit f8ef8eb fixed the shared strings class to automatically sanitize its serialized XML output to remove any control characters. However, this commit did not include tests that the shared strings actually removed the control characters when serializing to an XML string. * This tests confirms that the string with control characters is added to the shared strings, and that the control characters are removed from the string in question when serialized to XML.

In version 1.3.6, the shared strings are not sanitized to remove any control characters that may be present in the string. This causes excel files generated using shared strings to require repairs and lose data on opening.
This was fixed for later versions in f8ef8eb, so I cherry-picked the commit, fixing a conflict in
Axlsx::SharedStringsTable.to_xml_string. I also wrote a test to confirm the control characters are actually removed.Note that this PR is for version 1.3.6 of the gem. I'm not sure how you want to want to apply this patch, possibly as a point release?
