GPS/GNSS NMEA Sentence Processor Library needs updating

[djaus2]

GPS/GNSS NMEA Sentence Processor Library sample code
Main ussue is that Meadow.Foundation.Sensors.Location.Gnss.NmeaParsing is now depracated, as per Nuget documentation.
Add Nuget package Meadow.Foundation.Sensors.Location.Gnss to the app.
Modify line 9 to

using Meadow.Foundation.Sensors.Location.Gnss; //.NmeaParsing;

NmeaSentenceProcessor is part of that class

Note for what follows I was targetting Project Labs V3,

• Usual change of public class MeadowApp : App<F7Micro, MeadowApp> to:
  public class MeadowApp : App<F7CoreComputeV2>
• Change void Initialize() to
  public override Task Initialize()
• Change Device.SerialPortNames.Com4, to
  Device.PlatformOS.GetSerialPortName("COM1"), or whatever COM port is used. COM1 is the one in mikroBUS No. 1
• After serialPort.MessageReceived line add the Baud Rate setting eg:
  serialPort.BaudRate = 9600;
• At end of Initialize() insert:
  return base.Initialize();

@duduita Do you mind reviewing this to see if there is still an issue we need to resolve.

The NuGet package mentioned doesn't mention being deprecated here.

https://www.nuget.org/packages/Meadow.Foundation.Sensors.Location.Gnss.NmeaProcessor/

And it is the only package I find with that prefix: Meadow.Foundation.Sensors.Location.Gnss.

We do have a broken link to the class API docs at the top, though: NmeaSentenceProcessor name points to a 404 link. I found that class here instead, which somewhat aligns with the namespace issue mentioned originally: https://developer.wildernesslabs.co/docs/api/Meadow.Foundation/Meadow.Foundation.Sensors.Location.Gnss/NmeaSentenceProcessor/.
