Define indication cohorts

[edward-burn]

The following indications are listed in the protocol

•   Indications (recorded in the 7- and 30-day period before index date): 
o   Bloodstream Infection 
o   Bone and Joint Infection 
o   Cardiovascular System Infection 
o   Catheter-related Infection
o   Central Nervous System Infection
o   Eye, Ear, Nose, Throat or Mouth Infection
o   Gastrointestinal System Infection
o   Genito-Urinary Tract Infection
o   Lower Respiratory Tract Infection other than pneumonia
o   Pneumonia
o   Reproductive Tract Infection
o   Skin and Soft Tissue Infection
o   Surgical Site Infection
o   Other Infection

Perhaps we'd also want a general "any infection" cohort for a more general summary?

These definition would replace the current placeholders here: https://github.com/oxford-pharmacoepi/FluroquinolonesStudyathon/blob/62a280214685ea3e54bde8d5a485ef761208de92/1_StudyCode/RunAnalysis.R#L264
