[racket] Is there a way to specify a reader for the repl for a language?

I think a `configure-runtime` submodule (in the expansion of any module
using the language) is the right place for this kind of configuration.

The `configure-runtime` submodule is similar to `main`, it that it is
only used when the enclosing module is the main module of a program.

Instead of a direct `(current-readtable ...)`, I think you'll want a
direct `(current-prompt-read ...)`, where the prompt read handler uses
`(parameterize ([current-readtable ...]) (read-syntax ...))`.
