Feature request: preserve bold and italics

If possible, it would be great if LaTeX kit preserve bold and italics from the source text by surrounding the relevant passages with \textbf{} and italicized text with \textit{} in the output. Sorry I can't put together a pull request myself; my programming skills are not to be trusted.

No file or test is named. Locate the code that converts Google Sheets cell text and formatting into LaTeX output, then inspect how source text is currently represented; done means bold passages use \textbf{} and italic passages use \textit{} while preserving the surrounding text.
