Refactor repo

Currently misspelling extraction from wiktionary and applying this list to collect misspellings in wikipedias are in separate notebooks. We need to

• Re-organize the code (directories and files)
• Convert notebook functions into scripts

so that we can run the workflow across all language wikipedias and perform analysis.

Possible folders:

• Scripts
• Notebooks
• Resources (misspellings from wiktionary)
• Output (misspellings extracted from wikipedia)
