Support TCX files

[martin-ueding]

A user asked for TCX files, which are not supported yet. I'll have to look into this file format.

I've added https://github.com/alenrajsp/tcxreader, but there is some more work to do. Somehow the files start with spaces:

          <?xml version="1.0" encoding="UTF-8"?>
<TrainingCenterDatabase
  xsi:schemaLocation="http://www.garmin.com/xmlschemas/TrainingCenterDatabase/v2 http://www.garmin.com/xmlschemas/TrainingCenterDatabasev2.xsd"
  xmlns:ns5="http://www.garmin.com/xmlschemas/ActivityGoals/v1"
  xmlns:ns3="http://www.garmin.com/xmlschemas/ActivityExtension/v2"
  xmlns:ns2="http://www.garmin.com/xmlschemas/UserProfile/v2"
  xmlns="http://www.garmin.com/xmlschemas/TrainingCenterDatabase/v2"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns4="http://www.garmin.com/xmlschemas/ProfileExtension/v1">
            <Activities>
              <Activity Sport="Other">

And that confuses the parser:

Seems to work now.
