Functions
unsigned char	NMEA::checksum (std::string_view body)
std::optional< uint32_t >	NMEA::hexNumber (std::string_view digits)
	The value of digits when every one is a hexadecimal digit, with no sign or prefix; nullopt otherwise.
size_t	NMEA::splitFields (std::string_view text, std::span< std::string_view > fields)
	Preserve empty fields, including the final field. Return zero on storage overflow.
std::optional< Frame >	NMEA::frame (std::string_view text)
bool	NMEA::isStandardSentence (std::string_view text)
	A checked sentence from a standard talker, not a proprietary $P... sentence.
std::optional< Sentence >	NMEA::sentence (std::string_view text)
double	NMEA::degreesFromDegreesMinutes (double ddmm)
	Convert a signed ddmm.mmmm (or dddmm.mmmm) value; invalid values return NaN.
std::optional< double >	NMEA::coordinate (std::string_view field, std::string_view hemisphere, bool latitude)
std::optional< GGA >	NMEA::gga (const Sentence &input)
	Quality zero is a valid fix-loss observation with empty coordinates and optional hemisphere fields.
std::optional< int >	NMEA::utcMilliseconds (std::string_view field)
std::optional< UtcDate >	NMEA::rmcDate (std::string_view field)
std::optional< RMC >	NMEA::rmc (const Sentence &input)
std::optional< GLL >	NMEA::gll (const Sentence &input)
std::optional< VTG >	NMEA::vtg (const Sentence &input)
std::optional< ZDA >	NMEA::zda (const Sentence &input)
GPSFixQuality	NMEA::fixQuality (unsigned quality, GPSFixQuality autonomous)
	Autonomous GGA does not distinguish 2D/3D; the caller supplies its independently resolved quality.
std::optional< NavigationStatus >	NMEA::navigationStatus (const Sentence &input)
std::optional< GST >	NMEA::gst (const Sentence &input)
QByteArray	NMEAUtils::frame (QByteArrayView body)
	body as one "$<body>*hh\r\n" sentence, with uppercase checksum digits.
QByteArray	NMEAUtils::repairChecksum (const QByteArray &sentence)
	Rebuild a valid frame with its checksum and CRLF; short or malformed bodies are only terminated.
QByteArray	NMEAUtils::makeGGA (const NMEA::GGA &fix, const QTime &utc)
