Honor required badges to use command - Helps with Issue #51

[parithon]

Purpose

We need a way for broadcasters to limit who can use this command. This PR allows the broadcaster to set the required badges a user must have in order to use the command. Users who do not have the badge will be ignored. The broadcaster will always be allowed to use the command.

Changed files

• package.json Added a new setting to capture the required badges: twitchHighlighter.requiredBadges
• constants.ts Added the new setting to the constants.
• twitchChatClient.ts Forwards the requiredBadges (array) setting to the twitch server using the start params.
• twitchLanguageServer.ts Captures the badges when a user sends a message and verifies the user has a required badge before continuing to parse the message for our highlight command.
• twitchLanguageServer.test.ts Added the new parameter requirements for the parseMessage function and added tests to ensure the requiredBadges exists and fails (as we expect) when they don't.
