openhop-dev/openhop_core ? reverse-engineered prompt

Build me a Python library for running a MeshCore style LoRa mesh node on a Raspberry Pi or similar board.

I want it to talk to an SX1262 radio over SPI, let me start a node with a local identity, and handle the basic mesh stuff like routing packets, sending messages, working with group channels, advertisements, telemetry, and repeater features. It should be easy to use from a small async Python script, with a clear example that shows creating the radio, starting the node, and sending or receiving data.

Please also include the hardware support pieces for common boards like a Waveshare SX1262 HAT, and make sure the project is organized cleanly with examples and tests. If anything about the MeshCore protocol is unclear, look up the current docs online and match the existing behavior as closely as possible. Keep it compatible with Python 3.10 plus, and make it feel ready to install and try on real hardware.
