Loading information on noise and gain levels (e.g. from header file) to predict bad channels

I wondered whether there is an easy way to get information about the noise and gain levels of the channels, other than loading the header-textfile manually? It it does not seem to be loaded automatically into the raw-object or did I overlook something?

In MNE-Python we try not to make too many attributes public because it increases the number of things we need to support. For your use case is there a library like PyEDFLib that would do the job?

If not, reading the header text file might actually be the best way to go
