Feature Request: Extract more data

[sirdrakeistda]

Description

It would be nice to get more data from GPX files. For example number of satellites and all data from the extension part.

This is an example for a gpx section with data which could be imported:

<trkseg>
  <trkpt lat="34.837636" lon="15.02789063">
   <time>2021-12-11T00:05:49Z</time>
   <ele>23.72</ele>
   <sat>11</sat>  
   <extensions>
     <speed>0.000</speed>
     <accuracy>25.73</accuracy>
     <batterylevel>35.00</batterylevel>
     <useragent>API/0.1.0</useragent>
   </extensions>
  </trkpt>

Thank you for your great work. I like this tool very much.
