Add Kenya database

[shaunanoordin]

PR Overview

This PR adds the kenya database (for WildWatch Kenya)

The Kenya database...

• consists of 3 tables: aggregations, subjects, cameras
• the aggregations are for survey WF 11374 (production)
• the subjects are from subject set 77507 only. We're using a small pool for now to test that the classrooms work.
• the cameras list was provided by the WW Kenya team at San Diego Zoo

In this PR...

• the docker files are updated to ensure Datasette recognises the kenya files
• a kenya.zip was added to /data
  • ❗ Wait, something's not right here. The /data/kenya.zip ain't recognised for git add.
  • @camallen in commit 287802d, the .gitignore was updated to specifically "ignore the data file", i.e. data/**/* (Wait, how are the gorongosa.zip and darien.zip still in the repo? Does .gitignore not work retroactively on files that were already added?)
  • Q: is the .gitignore supposed to prevent additional .zip files to be added to the /data folder (e.g. to prevent gargantuan diffs from binary files), or is this some wildcard wonkiness? My default action is to disable .gitignore, git add kenya.zip, commit, then restore .gitignore, but I thought I'd check with you first.

Status

WIP, waiting on info on the .zip file.

Nice LGTM

Re the data - that is a scratch space for local dev and to avoid csv files (large) etc being added to the git repo accidentally I ignored that directory on purpose.

Simple way to get your data in is to:

1. Modify your local .gitignore to comment out this line https://github.com/zooniverse/classroom-maps-api/blob/4c4eab831b862edb47d52948ef11bbe14cbcb088/.gitignore#L2
2. check in your zip file (aiming for archives smaller than 10MB - we can switch away from zip archives if needed)
3. reset the .gitignore file to not accidentally check in data / csv files.

👍 Thanks Cam! I've git-added the Kenya.zip file so this PR is good to go. Noted on the 10MB recommended limit - at the moment I have Kenya sitting at 5MB, but I'll keep an eye on the size as we add more Subjects to the archive.
