Implements text chat settings

[TheCodeTherapy]

This PR implements text chat settings for the 3d-web-experience.

With this change, users can easily set up the text chat to be automatically visible and pinned by default when the app starts, and also provide options for the username hash to color feature, which improves chat readability by assigning colors deterministically to each username on the text chat.

The new Networked3dWebExperienceClientConfig options are:

• chatVisibleByDefault?: boolean (optional. defines if chat will be immediately visible and pinned when the app starts. If not provided, it will default to true);
• userNameToColorOptions?: StringToHslOptions (optional. defines hueThresholds, saturationThresholds, and lightnessThresholds for the logic that assigns a deterministic color per username. If not provided, it will default to the values illustrated on the usage example below.

Usage example for multi-user-3d-web-experience/client/src/index.ts:

const app = new Networked3dWebExperienceClient(holder, {
  sessionToken: (window as any).SESSION_TOKEN,
  userNetworkAddress,
  chatNetworkAddress,
  chatVisibleByDefault: true,
  userNameToColorOptions: {
    hueThresholds: [[10, 350]],
    saturationThresholds: [[60, 100]],
    lightnessThresholds: [[65, 75]],
  },
  animationConfig: {
    airAnimationFileUrl,
    idleAnimationFileUrl,
    jogAnimationFileUrl,
    sprintAnimationFileUrl,
    doubleJumpAnimationFileUrl,
  },
  skyboxHdrJpgUrl: hdrJpgUrl,
  mmlDocuments: [{ url: `${protocol}//${host}/mml-documents/example-mml.html` }],
  environmentConfiguration: {},
});

The example above already shows the default values for the userNameToColorOptions. This option can also be used in a future PR to set the same color for the label that shows above the character showing its user name.
