feat: create raw data loader and setup of repo

[arjunsridhar12345]

This PR attempts to address #3 by creating a module for loading the raw data using the data contract for the Dynamic Foraging experiment defined here: https://github.com/AllenNeuralDynamics/Aind.Behavior.DynamicForaging/blob/main/src/aind_behavior_dynamic_foraging/data_contract/_dataset.py.

Using this diagram as guidance: https://github.com/AllenNeuralDynamics/aind-software-docs/blob/main/diagrams/dynamic_foraging/low_level/dynamic-foraging-low-level-processing.svg

An initial example notebook has been made to try and show how to access the raw data:

In addition, the PR does some setup for the repo so it tries to align with the coding standards that were recently merged by a group of engineers from SIPE and Sci Comp as the current package template has not been updated yet. There may be things I missed or maybe messed up but at a high level is the following:

• Uses uv
• Uses ruff instead of black and flake8 with uv
• Runs pytest with uv
• Runs tests on pushes to dev and main
• Runs tests across the os matrix
• Updates the contributing file with the above
