Added a Scale=MatchAveragecase option

Description

I have added a Scale=MatchAveragecase option to complement Scale=MatchLowercase and Scale=MatchUppercase, it simply sets the Scale to the average of what MatchLowercase and MatchUppercase would do. This is usefull when you can't make up your mind whether to use MatchLowercase or MatchUppercase, or when neither looks good, as in the example below (where in my opinion, the MatchAveragecase version looks the best)

Todos

• Tests added to cover new/fixed functionality
• Documentation if necessary
• Code follows expl3 style guidelines

Minimal example demonstrating the new/fixed functionality

\setmainfont{TeXGyreSchola}
\newfontfamily\lc[Scale=MatchLowercase]{Fira Math}
\newfontfamily\uc[Scale=MatchUppercase]{Fira Math}
\newfontfamily\ac[Scale=MatchAveragecase]{Fira Math}
\begin{document}
\noindent
Lower {\lc and UPPER} CASE\\
Lower {\uc and UPPER} CASE\\
Lower {\ac and UPPER} CASE
\end{document}

Thanks! That’s a nice idea. I tried for a few minutes to think of a better name for the option but nothing jumped out at me.

I’m not working frequently on the fontspec code at the moment so if you don’t see anything happen here for a while please don’t hesitate to ping me again about this.
