- If no reset pin was set, calling standby() in the constructor
would enable the TCXO (XOSC) before the timeout was correctly set.
- This manifested as a BUSY timeout on the STM32WL5, first time after power
on reset.
- Clean up the general handling of BUSY timeouts, but also add some safety
margin to the base timeout just in case (not an issue, is only a stop-gap
to prevent the modem blocking indefinitely.)

For unknown reason, power output in this configuration is lower than it
should be (including when compared to the STM32Cube C libraries running on
the same board.
Suspect either the Nucleo board antenna switch or the power amplifier
registers are being set wrong, but the actual root cause remains elusive...

Support depends on hardware support in MicroPython.
Also includes some tweaks in the SX126x base class, to deal with slightly
different platform configuration on STM32WL55, longer timeouts, tx_ant
options, etc.
