Support parsing #\Replacement_Character about tree-sitter-commonlisp

[theHamsta]

The character issue should be fixed in #8

I added sly to the test suit and will go through the remaining failures:

until now I only tested on github.com/marcoheisig/Petalisp

Ok, all parsering errors (apart from string format parsing should be fixed now in sly)

❯ tree-sitter parse test/sly/**/*.lisp -q
test/sly/contrib/slynk-fancy-inspector.lisp     5 ms    (ERROR [111, 45] - [111, 47])

Fixed by #8

Fantastic, thanks for all those fixes :)
