new simulations with all parameters at once, reinstane VectorizedRNG, remove weights for household sampling, need to redo intervalsmodel again

found bug in VectorizedRNG, back to default. Also reran intervals model, and now should rerun model fitting.

added distinct vaccination/infection stages, immunization delay, and univariate figures showing more useful results with these changes

new output plots, alert mechanic bug fixed and mechanic changed to give alerts if coin flips exceed notification_threshold

add univariate snensitivity plots, some output code, added the model size and length to parameter tuple. New output is in /CovidAlertVaccinationModel/plots/univariate
