+The ESPNowCam library is a simple and direct video or data streamer designed for popular ESP32 devices, utilizing the ESPNow protocol. No need for IPs, routers, or credentials—keeping it straightforward and hassle-free! :D
 
 **This library is for general purpose**, as it accepts pointers to various types of data, including buffers, strings, images, or any byte-formatted content. This flexibility enables transmission of larger packages across different scenarios, not limited to cameras alone. For instance, a buffer of 4000 bytes takes approximately 1/9 of a second to transmit, resulting in a frame rate of around 9FPS.
