It's possible to end up with "recursive embeds" when two notes embed
each other. This happens for example when a `Note A.md` contains
`![[Note B]]` but `Note B.md` also contains `![[Note A]]`.
By default, this will trigger an error and display the chain of notes
which caused the recursion.
Using the new `--no-recursive-embeds`, if a note is encountered for a
second time while processing the original note, rather than embedding it
again a link to the note is inserted instead to break the cycle.

Previously, links referencing a heading (`[[note#heading]]`) would just
link to the file name without including an anchor in the link target.
Now, such references will include an appropriate `#anchor` attribute.
Note that neither the original Markdown specification, nor the more
recent CommonMark standard, specify how anchors should be constructed
for a given heading.
There are also some differences between the various Markdown rendering
implementations.
Obsidian-export uses the [slug] crate to generate anchors which should
be compatible with most implementations, however your mileage may vary.
(For example, GitHub may leave a trailing `-` on anchors when headings
end with a smiley. The slug library, and thus obsidian-export, will
avoid such dangling dashes).

Previously, partial embeds (`![[note#heading]]`) would always include
the entire file into the source note. Now, such embeds will only include
the contents of the referenced heading (and any subheadings).
Links and embeds of [arbitrary blocks] remains unsupported at this time.

Links within an embedded note would point to other local resources
relative to the filesystem location of the note being embedded.
When a note inside a different directory would embed such a note, these
links would point to invalid locations.
Now these links are calculated relative to the top note, which ensures
these links will point to the right path.
