Converted EN code blocks should not escape characters

- yarle v3.8.2 (run from `npx`)
- npm 7.4.3

I am really happy to have this tool, thank you 🙏

My notes make heavy use of code blocks, and I am finding the converted notes need a lot of cleanup, because characters such as `_` or `[` get escaped as `\_` or `\[` — even though they are contained within fenced code blocks ` ``` ` in markdown.

At this point I am just deleting the code blocks after conversion, then copy/pasting them from Evernote into Obsidian using ⌘+⇧+V which avoids the escaping...
