Global TC, TR, TS and EQ release

Global hazard coverage for TC (tropical cyclone), TR (tropical cyclone rain or torrential rain), TS (tropical cyclone surge) and EQ (earthquake). While the single hazards have not yet been calibrated, the whole structure is in place. Closest to reasonable results is hazard TC, others still need calibration for each country, mainly due to the fact that climada for the time being comes only with one reasonable damage function for TC. Other functions need currently to be provided by the user.
