Create a vaccine schedule for use with lancelot_parameters
vaccine_schedule(date, doses, n_doses = 2L)A single date, representing the first day that vaccines will be given
A 3d array of doses representing (1) the model group
(19 rows for the lancelot model), (2) the dose (must be length
2 at present) and (3) time (can be anything nonzero). The values
represent the number of vaccine doses in that group for that
dose for that day. So for doses[i, j, k] then it is for the
ith group, the number of jth doses on day (k - 1) + date
The number of doses in the schedule. Typically (and by default) this will be 2, but if using booster doses 3 (and in future we may extend further).
