Reasonably Scoped Branding Update (#299)

- Adds TsconfigPathsPlugin
- Custom icons, branding assets, and favicons now all live under
`/src/assets` in organized folders (Mirrors Browsertrix folder
organization and naming)
- Assets can now be referenced with `import: varName from
~assets/assetpath` app wide!
- SVGs continue to use `svg-inline-loader`, favicons are copied to
`/site/favicons` on app build
- Adds favicons to the main `index.html` page for ReplayWeb.page and
`embed.html` example page
- Replace README header with new branding
  - Lives under /assets because it's not app related
- Adds new webmanifest app icons
- Adds new Electron app .icns (macOS ) and .png (Windows & Linux) app
icons
- Replaces globe icon in the embed receipt with ReplayWebpage icon!
  - Adds lockup to the footer section
- Removes logo animation
- Removes logo values from `renderErrorReport()` in swmanager.ts in
favour of additional import statements
