PBR: Function for finding PBR quota
In NorskRegnesentral/rSPAMM: Population dynamics model for harp and hooded seals

Finding Potential Biological Removal (PBR) quotas

PBR(
  n0 = n0,
  n1 = n1,
  se0 = se0,
  se1 = se1,
  rMax = 0.12,
  Fr = 0.5,
  quota = c(0.14, 1 - 0.14),
  cv = NA
)

`n0`	Estimated current population size of 0 animals
`n1`	Estimated current population size of 1+ animals
`se0`	Standard error of estimate for n0
`se1`	Standard error of estimate for n1
`rMax`	Maximum rate of population increase (by default 0.12, commonly used for pinnipeds)
`Fr`	Assumed recovery factor
`quota`	Proportional catch of 0 and 1+ animals

Returns Minimum projected population size (Nmin) and Potential Biological Removal (PBR), along with the PBR divided by 0 and 1+ animals given specified quota
