Fixes: Issue 26

Some notes on installation before you begin testing the repo:

1. Package installation: I have switched to uv, and made a minimal list of packages (i.e. skipping auto-sklearn and other problematic packages). This means that install should happen smoothly without dependency issues BUT I cannot guarantee that the files NOT touched by this PR work as expected.

2. Spark installation: On Mac, I needed to do a few additional steps to get Spark (for parallelized dataframe operations) to work:
   a. brew install openjdk@17
   b. export JAVA_HOME="$(/usr/libexec/java_home)" && export PATH="$JAVA_HOME/bin:$PATH"

Description

Re-implement homelocations module to make it more lightweight

Changes

• Made a new homelocation/ folder that reimplements everything in cider/home_location.py

  • schemas.py adds schemas to enforce structure for the data required for home location inference. These functions are originally captured by functions in cider/data_checker.py cider/datastore.py, cider/data_format/data_format.yml and configs/config*.yml
  • inference.py implements the actual inference algorithms in home_locations.py (HomeLocator.get_home_locations and HomeLocator.accuracy)
  • plotting.py re-implements a less fancy version of HomeLocator.map
  • dependencies.py reimplements helpers.plot_utils.voronoi_tesellation -- this was a wrong turn I took ( I thought I would need this for making maps / plots, but decided not to use it because Voronoi tessellations are only used to plot population maps)

• Added tests for all the implemented functions

• Moved notebooks -> old_notebooks; added new notebook for testing to notebooks

Future Tasks:

• We might have to move the schemas to outside this module since CDR / Antennas get reused for other modules
• We might also have to move some of the dependencies / plotting out of this module since they might get re-used
• The linting GHA fails because the rest of the repo is not up-to-date, but the cider/homelocation/ and tests/ modules are properly linted
• Need to add GHA for unit tests
• Need to add Makefile config for tests, freshenv install, etc.

How has this been tested?

• Run pytest tests/test_homelocation.py from the root of the repo
• Run the notebook notebooks/homelocation.ipynb and check everything works (variations for homelocation inference are thoroughly tested with the tests/; the notebook simply demonstrates a pipeline and comparison with the old way of doing things).

To-do before merge

• Remove all code related to the reimplemented functions here
