Add the epub reader from EdgeUWP to Edge Chromium.

PHGJ_1957 From my experience, Frieda is not an equal to Edge in the speed of load/paging turning or rendering as Edge was. It also lacks settings to use the default settings for the book, which makes the reading experience less than pleasant. Unfortunately, none of the epub readers for Windows have what I would consider to be an equivalent experience to what iOS provides out of the box. I traded in my iPad for a Surface Go because I thought I could finally had the right size device and reader app to so on Windows, but now I fear I may regret that choice. There are already warnings in the classic Edge that they will disable epub reading in the near future, which seems unnecessary.
