Allow user to override pypprint

[soraxas]

This PR allows user to define their own pypprint.

Example

I can define a custom config at $PYP_CONFIG_PATH as follows:

import numpy as np
import plotly.express as pe
import matplotlib.pyplot as plt


def pypprint(*args, **kwargs):  # type: ignore
    from typing import Iterable
    import sys

    if len(args) != 1:
        return print(*args, **kwargs)

    x = args[0]

    if "matplotlib" in sys.modules:
        import matplotlib.pyplot as plt

        if any(isinstance(_x, plt.Artist) for _x in x):
            return plt.show()

    if "plotly" in sys.modules:
        import plotly.graph_objects as go

        if isinstance(x, go.Figure):
            return x.show()

    if isinstance(x, dict):
        for k, v in x.items():
            return print(f"{k}:", v, **kwargs)
    elif isinstance(x, Iterable) and not isinstance(x, str):
        for i in x:
            print(i, **kwargs)
        return
    else:
        return print(x, **kwargs)

then, running

pyp 'plt.plot([0,1,1.5])'

automatically open the plot for you:)

*Note, the return statement simply allows me to short-circuit the flow; and the checking on sys.modules helps to avoid unnecessary import of modules if the modules is not already imported

Thanks, this is a neat feature!

However, the rest of pyp config is able to recursively reference other definitions in config (e.g. imports or other functions), which pypprint defined in this way would not. I'll take a shot at implementing that + adding some tests when I get some time.

Any new updates?
