Calculates FCL state

1	get_fcl_state(N)

`N`	Matrix of population abundances, where `nrow = 3`, and `ncol = n_patch`.

This function calculates the food chain length state of each patch at each time step in the IGP simulation. This is used internally.

numeric vector of length = n_patch. FCL state 0 = no species, 1 = B only, 2 = B + C, 2.5 = B + P, 3 = B + C + P

# simulate abundance matrix
# nrow = n_sp = 3
# ncol = n_patch = 10
N <- matrix(rpois(3 * 10, lambda = 1), nrow = 3, ncol = 10)

# make sure abundance of C and P = 0 when abundance of B = 0
N[,N[1,] == 0] <- 0

# calculate food chain length state
get_fcl(N)
