Refactor instrument module (#982)

* Only guess telescope names

* Build telescope description in SimTelEventSource

* Adapt hessio eventsource

* Adapt tests to work with gamma_test_large

* Start refactoring instrument classes

* Add test for isntrument hashing

* Better error for optics.from_name if no match is found

* Fix optics table

* More places to use gamma_test_large

* Add comment

* More fixes

* More fixes for simtel file

* Replace more hard coded telids

* More telid fixes

* Test event seeker only for its features

* Store n_mirrors in guessing result

* Add tests and fix CameraGeometry.equals

* Fix notebook

* Reduce repetition

* Make prod2 readable again but emit warning

* Remove tests that test for magic numbers of old simtel file

* Add missing assert in camera test

* Add entry for ASTRI with CHEC
