phpFITFileAnalysis

Changed-up to using Unix time by default instead of Garmin FIT timestamps.

See #33 for information.

An option can be passed to use Garmin FIT timestamps:

$options = [
    // false by default!
    'garmin_timestamps' => true
];
$pFFA = new adriangibbons\phpFITFileAnalysis('my_fit_file.fit', $options);
