Move get_input function into utils.py and update the call to get_input in coder.py to use the new utils.get_input function.

# Context:
USER: move get_input into utils. pass in history_file and fnames as params rather than referencing them with self.
ASSISTANT: To move the `get_input` function into `utils.py`, we will remove it from the `Coder` class in `coder.py` and add it to `utils.py`. We will also update the function to accept `history_file` and `fnames` as parameters.

```python
coder.py
<<<<<<< ORIGINAL
    def get_input(self):
        inp = ""
        multiline_input = False

        style = Style.from_dict({'': 'green'})

        while True:
            completer_instance = FileContentCompleter(self.fnames)
            if multiline_input:
                show = ". "
            else:
                show = "> "

            try:
                line = prompt(
                    show,
                    completer=completer_instance,
                    history=FileHistory(self.history_file),
                    style=style,
                )
            except EOFError:
                return
            if line.strip() == "{" and not multiline_input:
                multiline_input = True
                continue
            elif line.strip() == "}" and multiline_input:
                break
            elif multiline_input:
                inp += line + "\n"
            else:
                inp = line
                break

        print()
        return inp

def get_input(history_file, fnames):

    style = Style.from_dict({'': 'green'})

        if multiline_input:

        try:
            line = prompt(
                show,
                completer=completer_instance,

        except EOFError:

        else:
            inp = line
            break

    print()
    return inp
>>>>>>> UPDATED
```

Now, update the call to `get_input` in `coder.py` to use the new `utils.get_input` function:

```python
coder.py
<<<<<<< ORIGINAL
        inp = self.get_input()
=======
        inp = utils.get_input(self.history_file, self.fnames)
>>>>>>> UPDATED
```
