/**
 * This is the library's event emitter. Use this to listen to internal events of the library like so:
 * ```javascript
 * ev.on('event', callback)
 * ```
 *
 * The event you want to listen to is in the format of [namespace].[sessionId]
 *
 * The event can include wildcards.
 *
 * For example, to listen to all qr code events, the event will be `qr.**`. e.g:
 *
 * ```javascript
 * ev.on('qr.**',...
 * ```
 *
 * Listen to all sessionData events
 *
 * ```javascript
 * ev.on('sessionData.**',...
 * ```
 *
 * Listen to all events from session1
 *
 * ```javascript
 * ev.on('**.session1',...
 * ```
 *
 * Listen to all events
 *
 * ```javascript
 * ev.on('**.**',...
 * ```
 *
 * ev always emits data, sessionId and the namespace which is helpful to know if there are multiple sessions or you're listening to events from all namespaces
 *
 * ```javascript
 * ev.on('**.**', (data, sessionId, namespace) => {
 *
 *  console.log(`${namespace} event detected for session ${sessionId}`, data)
 *
 * });
 * ```
 *
