New version breaks compatibility with non-dask data

[stephenpardy]

Describe the issue:

Version 0.3.0 includes changes that break the compatibility of some functions - notably the families - to work with non-dask data.

As one example, the newton function changed the line calculating betas from:

beta = np.zeros_like(X, shape=p)

to:

beta = np.zeros_like(X._meta, shape=p)

which will fail for any non-dask data.

Minimal Complete Verifiable Example:

from dask_glm.algorithms import newton
import numpy as np
X = np.random.random((100, 3))
y = np.random.random((100,))
newton(X, y)

Anything else we need to know?: If this is an intended change, would be good to call out the reason for it (sorry if I missed it).

Environment: Local (macbook pro - M1)

• Dask version: 2023.3.0
• Python version: 3.10.10
• Operating System: Mac osx
• Install method (conda, pip, source): pip

Thanks @stephenpardy ! We'll take a look. As a heads-up tomorrow is a national holiday in Germany (where some of the folks that are likely to work on this are located) so we may be slow to respond until Thursday.

Git bisect'd to #87, will address from here.
