Detailed Description

FDO2-G2 UART command client (PyroScience data sheet v5, §4).

Implements the FDO2-G2 command set: #VERS, #IDNR, #MOXY, #MRAW, #LOGO. Lines are ASCII, terminated with \\r (optional \\n after \\r per §4.1). If optional CRC is enabled (#CRCE 1), responses end with : C before \\r (§4.2), C being the CRC-16/MODBUS of every byte before the : in decimal; the driver verifies it and rejects a mismatch with DriverError::CrcMismatch.

Default UART is 19200 8N1 after power-up; allow ~1 s settle time before the first transaction.
