Estimate the number of bed nets required to match usage target

Usage

commodity_nets(
  usage,
  use_rate,
  distribution_timesteps,
  crop_timesteps,
  half_life,
  par,
  ...
)

usage: Desired target usages (%) to model. Numeric scalar or vector.
use_rate: Usage rates. Numeric scalar or vector.
distribution_timesteps: Distribution timesteps (days). Numeric scalar or vector. By default, we can assume that net distributions happen on the first day of each year. For example c(1, 366)
crop_timesteps: Crop estimate timesteps (days). Numeric scalar or vector. If assuming distributions occur on the first day of each year, a reasonable assumption would be that the crop (and therefore corresponding usage) estimates were taken at the mid-point of each year. For example c(1, 366) + 183.
half_life: Country-specific net half-life in days. Numeric scalar or vector.
par: Population at risk estimates. Numeric scalar or vector.
...: additional arguments for the crop_to_distribution function in netz
