https://github.com/webrecorder/archiveweb.page/pull/199.
## Changes
- Organizes published files more cleanly, using `dist/types` folder as
the target for type declarations and sourcemaps
- Configures type field in `package.json`
- Updates ESLint & its config
- Sets up type-informed linting rules mirroring browsertrix
- Adds a bunch of other useful eslint and eslint-typescript rules, and
applies auto-fixes to the codebase
- Cleans up a bunch of types throughout the codebase, particularly parts
of the code used by ArchiveWebPage
- Changes `ItemIndex#_deleting` from `private` to `protected` so that a
part of AWP that extends it can do so properly
- Makes a bunch of previously-implied [non-null
assertions](https://www.typescriptlang.org/docs/handbook/2/everyday-types.html#non-null-assertion-operator-postfix-)
explicit
- Updates `URLResource` and `ItemType` types (and renames `Item` →
`ItemType` to disambiguate from the `Item` class)
- Removes `node-sass` and replaces it with `sass-embedded` for much
quicker installs and compilation
- fix ipfs for apple m1 osx builds by adding extra binary prebuilds (for now)
- use <profile directory>/js-ipfs for ipfs repo
- update to js-ipfs 0.10.6
bump to 1.5.2
- use seperate plugin dirs, plugins-mac, plugins-win, plugins-linux for the flash plugin to support
simultaneous win and linux build
- enable notariziation, use env vars to run on travis
- ci runs 'yarn run dist', skip docs build from ci
- pass GH_TOKEN to docker containers
- update to latest electron packages
