Please add cadence support for the TrackPoint

It is commented as Not handled yet so unsurprisingly I don't see it in wTCX.dart. How hard is to add it? I'll dig into the xsds.

It looks like to me that Cadence is not even an extension to the Trackpoint element but a simple member.

    <xsd:complexType name="Trackpoint_t">
            <xsd:sequence>
                    <xsd:element name="Time" type="xsd:dateTime"/>
                    <xsd:element name="Position" type="Position_t" minOccurs="0"/>
                    <xsd:element name="AltitudeMeters" type="xsd:double" minOccurs="0"/>
                    <xsd:element name="DistanceMeters" type="xsd:double" minOccurs="0"/>
                    <xsd:element name="HeartRateBpm" type="HeartRateInBeatsPerMinute_t" minOccurs="0"/>
                    <xsd:element name="Cadence" type="CadenceValue_t" minOccurs="0"/>
                    <xsd:element name="SensorState" type="SensorState_t" minOccurs="0"/>
                    <xsd:element name="Extensions" type="Extensions_t" minOccurs="0">
                            <xsd:annotation>
                                    <xsd:documentation>You can extend Training Center by adding your own elements from another schema here.</xsd:documentation>
                            </xsd:annotation>
                    </xsd:element>
            </xsd:sequence>
    </xsd:complexType>

The only thing is that it must be an integer and it's an unsigned byte, so cannot be negative or larger than 254.

    <xsd:simpleType name="CadenceValue_t">
            <xsd:restriction base="xsd:unsignedByte">
                    <xsd:maxInclusive value="254"/>
            </xsd:restriction>
    </xsd:simpleType>
