Constant nmea::SENTENCE_MAX_LEN

pub const SENTENCE_MAX_LEN: usize = 102;

The maximum message length parsable by the crate.

From gpsd:

We’ve had reports that on the Garmin GPS-10 the device sometimes (1:1000 or so) sends garbage packets that have a valid checksum but are like 2 successive NMEA packets merged together in one with some fields lost. Usually these are much longer than the legal limit for NMEA, so we can cope by just tossing out overlong packets. This may be a generic bug of all Garmin chipsets. NMEA 3.01, Section 5.3 says the max sentence length shall be 82 chars, including the leading $ and terminating \r\n.

Some receivers (TN-200, GSW 2.3.2) emit oversized sentences. The Trimble BX-960 receiver emits a 91-character GGA message. The current hog champion is the Skytraq S2525F8 which emits a 100-character PSTI message.
