Support for maritime units?

Would it be a good idea to implement nautical mile and knots? That is, nmi and kn or kt?

[ypearson]

why knot?

[UPC-PaalDriveklepp]

NMEA RMC messages contain the speed in knots, and knots are closely related to nautical miles. It is just a velocity and is easily convertible.

It would be nice to be able to do:

SI::knots_t parseNmeaSpeed() { /* implemenmtation */ }
void sendSpeed(const SI::metre_per_second_t& speed) { /* implemenmtation */ }

sendSpeed(parseNmeaSpeed(nmeaString));

Not sure exactly how it would look. Maybe it would also need a SI::unit_cast<>

Edit: @ypearson I think I got the joke... 🚶 🏠

I think you have a good idea =) More units!

I'll consider adding them probably in their own header as a special unit of the length dimension
