notebooks don't handle reader macros well

[Cyrik]

This is mostly a problem around clj-kondo ignore statements but also happens with other reader macros.

#_{:clj-kondo/ignore [:clojure-lsp/unused-public-var]}
(def a 1)

Produces two cells, where the first only contains #_.

This is probably happening because the LispTokenCursor calva uses to walk the file ignores commented s-expressions.
