GPX files from Zepp App fail validation #20

Closed karololszacki closed 1 year ago

karololszacki commented 1 year ago

GPX files generated with Zepp App (formerly Amazfit, a Xiaomi sub-brand) fail the validation. The guessGPXVersion function assumes it's a GPX format 7.7, which does not exist - when it's just the Zepp App version...

The file looks like this:

<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
