Develop the generator code

[akorosov]

Questions about generators:

In a simple case one input (sar), one output (CT) with the same size do we need just one generator? In the same case, do we need just one generator for training and validation data?

In a more complex case, a typical workflow:

• one input from sar at input layer
• another input from amsr2 at intermediate layer
• output (CT) at output layer How many generators do we need?

Parameters for generator:

• which bands to use
• which files to use (list of files or mask)
• at which layers to add the data
