Use periodic messages on M10SPG #57

Open AngusJull opened 1 week ago

AngusJull commented 1 week ago

Periodic messages offer a number of benefits over regular polling

No time waiting for a response
Output of message as soon as they are available
Less busy reading
Easier to configure output of multiple message types

Also made a couple other changes

Added a context structure for the gps
Added a function for also sending a valset message to simplify using them
Removed the timeout for read, the sensor will attempt to read a message 10 times, evenly spaced, instead of checking the monotonic clock
Added a way to check if a message is of a certain type. The array of message headers will be useful for a polling interface in the future, if that's required.

Closes #45 - this is a good start on periodic message reception.
