OpenXML Filter: XLSX: extract inline strings for translation

Worksheets may keep not only references to shared strings and formulas but contain inline strings. Please take a look at the corresponding part below:

        <row r="2" spans="1:1" x14ac:dyDescent="0.25">
            <c r="A2" t="inlineStr">
                <is>
                    <r>
                        <t xml:space="preserve">Rich text inline with </t>
                    </r>
                    <r>
                        <rPr>
                            <sz val="11"/>
                            <color theme="1"/>
                            <rFont val="Times New Roman"/>
                            <family val="1"/>
                            <charset val="204"/>
                        </rPr>
                        <t>Times New Roman</t>
                    </r>
                </is>
            </c>
        </row>

There is no support for such strings extraction at the moment. For more details please refer to the attached document.
