Compatibility with translated ARC-like REDCap projects

[tedinburgh]

Users can download CRFs from BRIDGE using a translation of ARC to French, Spanish, Portuguese (possibly more to come). This won't change variable names in the REDCap data or data dictionary, but will change values.

Affects:

• vertex/getREDCapData.py: is_yesno, combine_unlisted_variables, harmonise_age, convert_onehot_to_binary, initial_data_processing, get_df_map, get_redcap_data
• vertex/layout/filters.py: depends if the filters are always in English?
• vertex/io.py: config_defaults
• vertex/IsaricAnalytics.py: get_modelling_data

Changes needed:

• Add language to config file (vertex/io.py)
• Filters always in English (vertex/getREDCapData.py, vertex/layout/filters.py)
• Preprocessing to accommodate different languages, for now with if/else statements about language but we should have a better long-term solution (vertex/getREDCapData.py, vertex/IsaricAnalytics.py)
• Conversion tables for units in other languages (see Update conversion table #6)
