Description of feature

Hi there.
I think Sarek is in a good place with the current ASCAT implementation, but I'd like to point towards two things that I think would be helpful for the community.

• The function ascat.aspcf() (found in the ascat module) accepts a parameter penalty which controls the sensitivity of the tool to potential segment breakpoints. The default is 70 which is usually fine, but for individuals using panel/wes data being able to change this value might be helpful - any chance of exposing this as a param?

Kind regards,
George
