Fix crash recovery

[kbenoit]

Implements better error handling and better crash recovery using the environment approach from the loop.

• Adds lots of tests
• Solves Progress bar skips the first document #15 on the progress bar
• Removes Remotes requirement for quanteda.tidy, since the package should be able to work on its own with quanteda.tidy::mutate(), without issues, if we have written it correctly.
