Implement subscript

This ticks of the ~ which is also used for strikethrough ~~text~~,
so we hook into that function and perform the transformation.

Tests are also added.
Add superscript

Similar to subscript, except the superscript gets it own inline
callback for '^'.

Tests added as well.
Redo both sub- and superscripts

Do our own simple parsing, which seems to work ok. Follow pandoc
in that spaces are not allowed, unless they are escaped.

Update the tests as well.
