cards: add methods to help erasing of file contents
Resetting the contents of a file before re-writing it with parameters
might be helpful when implementing the currently empty erase() methods
of the various card implementations. Lets add two methods, one for
resetting a binary file and one for resetting a specific record in a
record oriented file
