Function parse_dprs 

pub fn parse_dprs(sentence: &str) -> Result<DprsReport, DprsError>

Parse a DPRS sentence into a DprsReport.

The sentence must start with $$CRC<4hex>,. The CRC field is parsed but not validated here — callers that want to verify it should compute super::compute_crc over the body bytes after the comma and compare against the 4-hex value between $$CRC and ,.

Errors

• DprsError::MissingCrcPrefix if the sentence doesn’t start with $$CRC
• DprsError::TooShort if shorter than the minimum viable length
• DprsError::MalformedCoordinates if lat/lon fields fail to parse
• DprsError::LatitudeOutOfRange / DprsError::LongitudeOutOfRange
• DprsError::InvalidCallsign if the callsign field is invalid
