bb's clojure.core/read requires LineNumberingPushbackReader

problem

clojure.core/read's doc says the stream must be an instance of java.io.PushbackReader or some derivee. While this is true in clojure, in babashka if that reader is used, I get the error

Type:     java.lang.IllegalArgumentException
Message:  No implementation of method: :get-line-number of protocol: #'clojure.tools.reader.reader-types/IndexingReader found for class: java.io.PushbackReader

Using clojure.lang.LineNumberingPushbackReader instead fixes this.

repro

The following script runs in clojure but not in bb:

(ns hello
  (:require [clojure.java.io :as io])
  (:import [java.io PushbackReader]))

(println (let [reader (PushbackReader. (io/reader *file*))]
   (read reader)))

expected behavior

bb shouldn't require LineNumberingPushbackReader.

@Cnly bb master should now support this (just pushed). Will write a test tomorrow, so I'll leave this open still.

Fixed.
