Error if output path doesn't exist

## Summary

If the output path doesn't exist, then shiv will fail with an error `FileNotFoundError: [Errno 2] No such file or directory`.

## Log

```
Traceback (most recent call last):

```

## To reproduce

1. `python -m venv .venv`
1. `. .venv/bin/activate`
1. `pip install shiv==1.0.3`
1. `echo "print('hello world')" >> __main__.py`
1. `shiv -e __main__.py -o dist/main --site-packages .venv/lib/python3.10/site-packages/`

## Expected behavior

Shiv should create leading directories if they do not exist.

## Versions

- python: *3.10*
- shiv: *1.0.3*

## Additional

Maybe something like
```py
target_dir = os.path.dirname(target)
if not os.path.exists(target_dir):
os.makedirs(target_dir)
```
should be inserted somewhere here https://github.com/linkedin/shiv/blob/eeec71f31a08203cffd184602eb6d10e30634126/src/shiv/builder.py#L93-L94

Start in src/shiv/builder.py around the target.open call cited in the issue, then reproduce the command using an output path such as dist/main. The change is done when shiv creates any missing leading directories and successfully writes the archive to the requested path.
