Improve lost and found mode

[RCGV1]

Platform

NRF52, ESP32, RP2040

Description

I think there are several ways lost and found mode could be improved:

• Reduce power in lost and found mode
• Enable precise location to avoid sending imprecise locations
• Reduce battery usage (Could stop forwarding packets)
• Allow position requests
• Make the node emit RF in a way to make it easier to direction find by making it a unique signal. (Doesn’t have to be Lora)
