Fails to match lists with spaces between lines (as ChatGPT tends to generate in its markdown lists)

[ailabs-software]

Hey there,

I found a bug where it fails to match lists with extra newlines (double spacing) between lines (as ChatGPT tends to generate in its markdown lists).

For example:

1. violin

2. piano

The fix is to change your listR regex to add a + after \n in the first group:
(?:(^|\n+)([+-]|\d+.) +(.(\n[ \t]+.)*))+

I'm not positive this doesn't break something else, but has worked for my use and I haven't found anything it breaks.

Not sure if you want to change it at this point, but thought I'd let you know.

I found this bug whilst porting your library to Dart because I needed a markdown parser that didn't add hundreds of kilobytes of JavaScript. Not a bad library for its size!
