integrate eslint

[odama626]

fixes #34

this adds eslint and moves to pretty-quick for prettier, but doesn't enable eslint yet -- want to get some of @tonyketcham's big Prs in first

Looking great!

Before this goes in, we should:

• start a branch off of this and subsequent draft PR that runs the formatting
• in that new branch, we can fix all the places ESLint screams about quick and dirty stuff we've done (particularly around types 😛)
  • this will likely take some time and might need both of us to chip away at it to resolve all the errors

Then after this goes in, we can:

• merge the ESLint formatting & fixes PR to main
• merge this branch into any existing or stale branches to run the formatting prior to merging main into said branches.
  • this will avoid any merge conflicts from formatting changes

#89

only 4 errors remain, and its around types

  29:33  error  Don't use `object` as a type. The `object` type is currently hard to use ([see this issue](https://github.com/microsoft/TypeScript/issues/21732)).
Consider using `Record<string, unknown>` instead, as it allows you to more easily inspect and use the keys  @typescript-eslint/ban-types

Nice one! Excited for this since it'll keep us in line & up our code standards

[odama626]

can we get this in? it's non-breaking, just really looking forward having pretty-quick

[odama626]

it's non breaking because lint:eslint isn't used by lint currently

[tonyketcham]

Yup - sorry for the delay on approving this one!
