Add ``context`` to errors

[sophielouisefeith]

Summary

💡 By Providing the user with more specific error context, the reason why the program fails will be more understandable for the non(technical) user(s) Additionally it would help finding bugs more efficiently

Possible solution design or implementation

💡 We've considered the following two options • Gathering information of the error in the main however this is not possible. • Using backtrace this would be to technical to the user. The best possible solution will be
implementing anyhow::context to all errors which are not manually implemented (e.g. wrapped errors such as IO etc).
