Fix get_ukb_data_dict() and get_ukb_codings()

These files have been removed from the UKB data showcase website.

• Temporarily update functions to download the old files from https://github.com/rmgpanw/ukb_backup_files
• Rewrite functions to recreate these files from those available at https://biobank.ctsu.ox.ac.uk/crystal/exinfo.cgi?src=accessing_data_guide (see "Data Dictionaries and Encodings")

Hello, thank you for the package and fixing the issues with the download link. However, I would like to ask that when I ran the tidy_clinical_events using this new dictionary from the backup. I encountered error "Columns instance and array don't exist.".

Hi @thiendattran, thanks for your message. tidy_clinical_events() seems to be working for me. Can you please provide a reproducible example (perhaps you could try adapting the ukbwranglr getting started vignette) and the output from sessionInfo()? Also, do other functions like make_data_dict() and read_ukb() work for you?
