NEW parse option:

As far as I can tell, we check for SOURCEPOS in inlines.c, and if the flag is set we annotate the node with sourcepos info, thereby allowing someone implementing their own renderer to also add sourcepos info to their output.

UNSAFE: (1 << 17)

To keep it inline with the deprecated SAFE flag, cmark-gfm.h defines UNSAFE after 1 << 3, so I've sorted it here accordingly.

I copied over all of the parse options and resorted the render hash. As described in the PR description, since the render method also initializes the parser with the same options integer, all of the parse options should be available as render options as well.
