Title: get rid of LinearMap's find_copy method

As with the now removed `get_copy` method, this is the same as just doing a copy in the caller and doesn't offer an advantage in either simplicity or performance. It duplicates the implementation of the `find` too.

This was still partially useful until the recent changes to the borrow checker that allow reborrowing.
