Feature: Added affiliate groups and compressed icon imgs

[melocoh]

closes #129

Description:
Add affiliate group found in the CSSS Discord.

Features

Under the route /affiliates in the mainsite, added the following:

• affiliate information to src/app/pages/affiliates/affiliates.ts
• each group's compressed (ideally around 50kB) logo to public/images/affiliates/.

Note

• Some of the discord links were created by discord user 'meloco' because the provided links from the CSSS server and SFSS club's site had already expired. Although these new URLs are set to "non-expiry", if the admin of the servers ever delete those links, then they will cease functionality.

A few changes requested.

Per our discussion, in affiliates.component.scsss, line 33, replace the .card-header styles with the one below, thanks.

.card-header {
  @include g.no-select;
  top: 0;
  text-align: center;

  backdrop-filter: brightness(50%);
  background-color: transparent;

  > p {
    margin: 0;
  }
}
