MAINTENANCE: code style improvements #101

[tkoyama010]

MAINTENANCE: code style improvements suggested by @jni #101 This is a sprint contribution in ScipyJapan2020 (#163) .

• [x] fully specified imports, dask.array instead of da, numpy instead of np.
• [ ] Code definitions in __init__.py is unconventional.

@GenevieveBuckley @jni I am moving __init__.py functions to _util.py . Is it a right place to move? or should I make a new *.py file?

This draft PR has been open too long and now has too many conflicts with the main branch, so I think we'll close it.

Scanning through this, it seems "code style improvements" here means three things. We could do these later in another PR (from a more up-to-date version of main branch):

1. Replace numpy with the abbreviation np (i.e. use import numpy as np everywhere)
2. Replace dask.array with the abreviation da (i.e. use import dask.array as da everywhere)
3. Move functions out of the __init__.py files, keeping those mostly empty except for imports and the __all__ dunder, etc.
