v0.5.0

Renault changed their API overnight; pyze 0.5.0 is therefore a required upgrade to continue accessing that API.

As well as that change (removing the "Kamereon token" and its uses) this release also includes the following changes:

• Include location data in status output (#49)
• Allow specifying that chargingInstantaneousPower should be interpreted as kilowatts, not watts (#59)
