Reorganize for packaging

[Ajstros]

Major Changes

• interfaces moved into a python/src folder
• Each chip that was in interfaces.py now has its own file in the interfaces/peripherals subpackage
• Documentation updates
• v0.0.6 of the package released on Test PyPI, still import as interfaces but can install with

py -m pip install --index-url https://test.pypi.org/simple/ --no-deps register-map

Check First

• [x] interfaces.py changes from daq_v2 branch not made in packaging branch due to files moving

These changes need to be made in the src/interfaces location before merging

• [x] import statements in test or sandbox files currently being used

Because interfaces is now in the src folder, the sys.path.append() trick used to add it to PATH to make it available for import is broken. It can be fixed by appending the new location, but I think it would be better to rely on users having the PyPI package installed. This is one discussion point. The boards.py file is not included in the package, and will remain in the python folder, meaning it will have to be imported using the sys.path.append() or similar trick.

Also, previous statements like below will no longer work because those chips are located in interfaces/peripherals now.

from interfaces.interfaces import CHIPNAME

These should be replaced with the following.

from interfaces.periperals.CHIPNAME import CHIPNAME

• [x] installation on other systems

I have only tested installing and using the package from Test PyPI on Windows. It should be tested on Mac as well and it would be good to test on Linux. The installation guide is in the doc/build/html/installation.html file on the packaging branch. Please comment installation issues on this pull request so they can be addressed.

Future Plans

It is important that files in this repository work with interfaces from the Test PyPI installation because I think it would be cleaner and more general to move the interfaces package, certain tests, Registers.xlsx, and a copy of the current bitfile to a separate repository which would eventually be uploaded to the main PyPI for installation.

The issues mentioned in these commits were not automatically closed. Maybe they have to be mentioned in the pull request commit itself? Anyway, I will manually close them.
