Small sizeof issue

[p0nce]

So I've ported md4c to the D language (https://github.com/p0nce/commonmark-d) and while translating I found a little mistake here:

https://github.com/mity/md4c/blob/master/md4c/md4c.c#L1690

I think you might mean:
sizeof(MD_REF_DEF*)
instead of:
sizeof(MD_REF_DEF)
which takes more memory.

Same issue here: https://github.com/mity/md4c/blob/master/md4c/md4c.c#L1707

and that's all I found. Amazing library!

Thanks for the bug report.

Nice to know about the port. I have added a link to it into README.md.
