Nested lists in description not supported

[andyrooger]

Nested lists don't seem to be supported when writing MD in the spec description.

Repro

info.description:

- item 1
- item 2
  - item 2.1
  - item 2.2
- item 2

Result:

* item 1
* item 2
* item 2.1
* item 2.2

This becomes a flat list, and after the first nested list ends the rest of the list is ignored.

Code

RapiPdf/src/markdown.js

Line 84 in 6a8055c

listInsert = v.ordered ? 'ol' : 'ul';

- this code doesn't seem to ever allow for nested lists.

It also does not allow multiline bullets, and seems to add bullets to any text following a list from what I can tell

markdown support in PDF is rudimentary, It do not support tables, complex alignments etc too.

However keeping this open now.
a PR will help me a lot here, otherwise I will take a shot at it to support at least the nested list

unable to commit to any timeline on it

#58 Seemed a nice way to tackle list nesting, tables and anything else in one go
