Disable log messages from TensorFlow

[marpet]

There are several log messages comming from TensorFlow when processing Idepix OLCI.
They should be disabled or at least the log level should be changed. So they are not shown by default.
e.g.:

modelDir = C:\Users\Marco\.snap\auxdata\idepix_olci\nn_ctp\nn_training_20190131_I7x30x30x30x10x2xO1 2019-09-19 09:11:18.351544: I tensorflow/cc/saved_model/loader.cc:242] Loading SavedModel with tags: { serve }; from: C:\Users\Marco\.snap\auxdata\idepix_olci\nn_ctp\nn_training_20190131_I7x30x30x30x10x2xO1 2019-09-19 09:11:18.360446: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 2019-09-19 09:11:18.371642: I tensorflow/cc/saved_model/loader.cc:161] Restoring SavedModel bundle. 2019-09-19 09:11:18.380097: I tensorflow/cc/saved_model/loader.cc:196] Running LegacyInitOp on SavedModel bundle. 2019-09-19 09:11:18.384236: I tensorflow/cc/saved_model/loader.cc:291] SavedModel load for tags { serve }; Status: success.
