SWIG-wrapped LIGOTimeGPSVector seems to cause memory leak

If I create LIGOTimeGPSVector's in Python using CreateTimestampVector they seem to not get automatically cleaned up and this causes memory to leak, e.g., running:

import lal
import lalpulsar

for i in range(1000):
    gpstimes = lalpulsar.CreateTimestampVector(100000)
    for i, time in enumerate(np.ones(100000) * 900000000):
         gpstimes.data[i] = lal.LIGOTimeGPS(time)

leads to the memory usage rising.

@karl-wette I assume this is because the DestroyTimestampVector function isn't getting linked with the LIGOTimeGPSVector type in the SWIG-wrappings, unlike the REAL8Vector does with it equivalent Create and Destroy functions. Can this be fixed?
