Updates required within maternal health modules during TLM

[joehcollins]

1.) Consolidate healthcare seeking behaviour logic across the modules and move to the HSB module
2.) Add some simple logic to allow for 'maximum' care seeking to be switch on for the modules
3.) Replicate logging as seen in HIV/Malaria where summary statistics are calculated for key outcomes every year and then stored directly in the logging

[joehcollins]

4.) Check twin rates

[joehcollins]

Additional fixes/areas for more thought going forward:
1.) Add relationship between anaemia and risk of PPH
2.) Adjust treatment effect of CS/AVD on stillbirth - also relationship between AVD failure and reduced risk of stillbirth through greater likelihood of CS?
3.) Broaden causes of antenatal sepsis (UTI etc)
4.) Removal foetal survival after maternal death in labour?
5.) Effect of chorioamnionitis colonisation on neonatal sepsis - as i'm only modelling maternal sepsis the incidence is much lower so the effect in the population is smaller
6.) Macrosomia - the distribution and the relationship with changing LBW prevalence
7.) Categorisation of intrapartum sepsis when services are maximised/minimised
8.) Definition of post term as 42+0.
9.) Only apply the effect of calcium/IFA to women assumed to be deficient (see LiST)

[joehcollins]

Also need to remove old logic related to squeeze factor (currently remains in place but with parameters set to 0)

See thesis appendix G - also see error r.e. apply_effect_of_anaemia function in pregnancy_helper_functions

[joehcollins]

GDM shouldnt occur in women with pre-pregnancy DM (effect may be double counted in risk of preterm RDS)
