Store extra metadata in attributes

[cparcerisas]

If I am not mistaken, at the moment the netcdf files do not store the information regarding:

• original sampling frequency
• sensitivity used for the calculation

Do you think it would be useful to add these? For us it would, especially the original sampling frequency.

Thanks!

@cparcerisas
Original sampling frequency was not included in the SoundCoop standard, but I agree that it is useful metadata.
Sensitivity is stored in the netCDF output, as the variable named... sensitivity. :)
