SX1262 is now finally stable due to these key changes: - Interrupt handling: To circumvent erratum 3.11 level interrupts are utilized. Unsure if this was actually an issue as only the DIO1 IRQ is installed, but it should be done nonetheless to avoid problems once more GPIO interrupts are used. - RadioLib HAL: Use the hooks for beginnig and ending a train of SPI transactions to lock and reserve the device, making it more reliable. Also, CS handling is removed as RadioLib manages this manually. - Board T-Lora Pager: Step down SPI frequency to reasonable rate
