Feature Request: Add GSV Sentence Parsing Support

[p3zhy]

Motivation

I am currently using the nmea0183 crate for my project, which involves GPS data processing for spoofing detection. I've noticed that the crate lacks support for parsing GSV (Satellites in View) sentences.
Spoofing attacks involve the generation of fake GPS signals, and having detailed information about the visible satellites, including their the PRN numbers, elevations, azimuths, and SNR , is crucial for identifying and mitigating such attacks. The addition of GSV parsing support will significantly contribute to the crate's capabilities in the context of spoofing detection.

Proposed Changes

I propose adding a new module for GSV parsing and implementing the necessary logic to parse GSV sentences. This enhancement will not only complete the set of essential NMEA sentences but also empower the nmea0183 crate to play a more critical role in applications focused on GPS data integrity and security.
