Add config creation script

Some parameters in the configs, such as the input paths for files and background noise files, the SNR and in some cases even the input format (MASA), are dependent on the configs. The random seed used in an experiment is also dependent on the lab which operates the test. To not introduce even more static configs which need to be maintained, a programmatic way for creating the config files is proposed by adding a script that generates the configs given an experiment type and a lab id.
