MAINT: clean up requirements.txt

Proposed changes

Resolves #126 and retains the bare minimum packages required to set up the environment. Some of the packages previously listed are still installed, but were probably added to the requirements as part of a pip freeze

Packages identified by setting up a clean environment and installing missing packages as it came up when trying to run app locally.

Ahh yeah, I guess I forgot to try uploading to database. I've added psycopg2 to the requirements in d238063.

My machine running Python 3.9 isn't compatible with numpy 1.17 anymore, maybe we could think of using numpy~=1.17 instead, and even adopting ~= more widely?

Yeah that sounds good. I've made the changes in the same commit to use ~=. Definitely prefer this to >= to ensure we don't accidently upgrade to a major change breaking existing functionality. I've been testing in Python 3.8 - none the less, running pip install -r requirements.txt installs the following for me:
