What is not working? What did you try?

According to the Markdown Spec, a line should end with two Spaces to make a break (https://www.markdownguide.org/basic-syntax/#line-breaks)
However, it seems to ignore the two spaces.
I added some quick fix into breaklineparser.h:

line = std::regex_replace(line, re, replacement);
if (line.ends_with(" ")) {
line.append(replacement);

This works unfortunately only with C++ 20
Reason for writing it this way is to avoid to replaces 2 Space in the middle of a line by

To get a br-Tag you can use \r\n - also documented at https://github.com/progsource/maddy/blob/master/docs/definitions.md#break-line

I intend to follow the CommonMark Markdown specs closer with maddy 2.0 which I'm still working on.
