SlimeVR USB-HID dongle for trackers over ESP-NOW

This is a USB-HID dongle code for M5AtomS3. The sensor data is received over ESP-NOW.

SlimeVR server v0.12.0 rc.1 introduced USB-HID sensor support. This code uses this feature.

Not tested well.

USB接続の無線ドングルのコードです。M5AtomS3で動きます。センサーからはESP-NOWでデータを受信します。

SlimeVR server v0.12.0 rc.1 ではUSB-HIDのサポートが追加されていて、それを利用しています。

十分にはテストされていません。
