Feat/add constants

Public API Changes

Description

We use rclnodejs to provide type information on ros message types only. This is so we can run without having a ros installation. The current exported types to have constant values. This allows us to define type enums for constants.

Changes

  export interface MsgFwForkData {
    timestamp: builtin_interfaces.msg.Time;
    timestamp_us: number;
    position: number;
    status: number;
  }
  export interface MsgFwForkDataConstructor {
    readonly STATUS_NONE: number;
    readonly STATUS_STOPPED: number;
    new(other?: MsgFwForkData): MsgFwForkData;
  }

to

  export interface MsgFwForkData {
    timestamp: builtin_interfaces.msg.Time;
    timestamp_us: number;
    position: number;
    status: number;
  }
   export enum MsgFwForkDataConstants{
    STATUS_NONE = 1,
    STATUS_STOPPED = 2,
  }
  export interface MsgFwForkDataConstructor {
    readonly STATUS_NONE: MsgFwForkDataConstants.STATUS_NONE;
    readonly STATUS_STOPPED: MsgFwForkDataConstants.STATUS_STOPPED;
    new(other?: MsgFwForkData): MsgFwForkData;
  }
