Classifications refactor

[jatkinson1000]

Closes #39
Consider also tackling #24

Refactor excessively long classifications file into several separate ones for each type of classification (plus general utils file).

It would be nice for the code to continue functioning as it previously did with

import archeryutils.classifications as class_func

rather than having to import each type of classification (indoor, outdoor, etc.) separately.
I have made an effort to do this using the classifications module __init__.py but it's not quite working.
@LiamPattinson is there any chance you could cast an eye and advise me what is best to do?
This could also be related to issue #3

TODO:

• Update examples notebook

Sorry, I'm not really sure what behaviour you're trying to retain. Please could you post example snippets of how you'd like things to work and how things have to work instead due to this PR?

[jatkinson1000]

Basically I want it to work the same as previously, so import archeryutils.classifications as class_funcs but because classifications.py has been broken up I now have to import each file separately, e.g. import archeryutils.classifications.agb_outdoor_classifications as class_funcs_out.

I tried to make it so that I could have all of the functions in these files wrapped up into classifications with the __init__.py but it doesn't seem to be working.

[LiamPattinson]

I think I've figured it out. In your top-level __init__.py, you have:

from archeryutils.classifications import classifications

So when you import archeryutils.classifications, you're actually importing the module archeryutils.classifications.classifications, which is now an empty module. It should work if you change the top-level __init__.py to instead say:

import archeryutils.classifications as classifications

[jatkinson1000]

I think I've figured it out. Change the top-level __init__.py to instead say:

import archeryutils.classifications as classifications

M8 that's done it.
Thank you so much, pypack guru.

Adding classification tests so that this PR will also close #23
This is necessary here to ensure everything is working OK after a major refactor.
