Gsof Protocol

This crate understand the GSOF Protocol from Trimble, is used to communicate data from GNSS Sources (GPS).

With the time I can implement all the tables, but now are only the useful for the job purpose.

Can be used as command as stream

``` nc HOST port | ./target/debug/read_stream

```

or connecting directly to the source.

``` ./target/debug/read_socket --host HOST --port PORT

```

Also can be used as library with other crates. Only need a BufReader and import the *GsofData struct.

You can check the code to understand how to use.
