Allow alternative ordered list indicators like a. i. A.

[jurmous]

I am dealing with converting a legal document to markdown to be shown with this library.

I would like to show ordered lists with different types of ordered list style types like with i. a. A. or I.

Just like what Github is doing below:

1. first item i. sub 1 ii. sub 2
2. second item a. sub 1 b. sub 2
3. third item A. sub 1 B. sub 2

Currently the other types of ordered list items besides numeric are not detected and thus they are rendered with plain paragraph tags.

Image from the output:

HTML supports other list types through the type tag or list-style-type css attribute. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/ol#attr-type
