* Add `jupyter-repl-syntax-propertize-function`. This allows packages like
`rainbow-delimiters-mode` to work regardless of what is printed as output of
a REPL cell by setting the syntax-table property on parenthesis in REPL
output.
* Fix an issue with the Julia REPL which would cause `syntax-ppss` to
report the wrong parenthesis depth due to the `]` character of the REPL
package mode. Thus interfering with how `rainbow-delimiters-mode` works.
* Ensure that the kernel language's syntax table is used when fontifying and
adding syntax properties.
This method allows kernel languages to do transformations of a src-block's code
based on the parameters supplied to the src-block before sending the code to
the kernel. The method is called in `org-babel-expand-body:jupyter`. Currently
the only parameter supported is the `:dir` option of a src-block.
* Define `jupyter-load-language-support` which takes a client and loads the
language support definitions of the client's kernel language.
* Call `jupyter-load-language-support` when initializing a REPL buffer in
`jupyter-repl-mode`. Note this also takes care of loading the kernel support
for a `jupyter-org-client' since a REPL buffer is setup before evaluating any
`org-mode` source code blocks.
* Move language specific methods to their own files named `jupyter-LANGUAGE.el`
