Update library to Contributors library standards

[maxdeviant]

This PR updates purescript-now to adhere to the Contributors library guidelines.

This is part of the purescript-contrib/governance#13 effort.

Once this is merged we'll need issues for the following items:

• Adding a "quick start" guide
• Adding tests

Thanks! Since CI isn’t yet running via GitHub Actions, would you mind sharing whether the build & test commands succeed (sometimes the new eslint config will fail, for example).

npm run build is failing with the following error:

λ npm run build

> @ build /home/maxdeviant/projects/purescript-now
> eslint src && spago build --purs-args '--censor-lib --strict'

That error happens when purescript-psa isn't installed. If you don't have that on your system, then try running just:

npx eslint src && spago build

[maxdeviant]

Alright, looks like we're good!

λ npm run build

> @ build /home/maxdeviant/projects/purescript-now
> eslint src && spago build

[info] Installation complete.
[info] Build succeeded.

λ npm t

> @ test /home/maxdeviant/projects/purescript-now
> spago test --no-install

[info] Build succeeded.
🍝
You should add some tests.
[info] Tests succeeded.
