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.

This refactors the Context to maintain a list of all the files which
have been processed so far in a chain of embeds. This information is
then used to print a more helpful error message to users of the CLI when
RecursionLimitExceeded is returned.
