Determine limiting factor in growth

For each timestep in the growth output matrix, determine the factor most likely to be limiting growth.

Usage

get_limiting(output, spec_params)

output: matrix, direct output of 'grow_macroalgae' function (can be sparse)
spec_params: a named vector of site-specific parameters - same as input to 'grow_macroalgae' function

vector of limiting factors at each timestep

This function gives an idea of what factor(s) limit growth at each timestep. The choices (in order) are:

T_lim
I_lim
S_lim
Q_lim - internal nutrient quotient
Ns_to_Nf - not enough stored nutrients (Ns) were available to be fixed at maximum rate
Nf_loss - more Nf was lost than fixed
conc_nitrate/conc_ammonium/conc_other - there were not enough ambient nutrients to be taken up at the maximum rate
Ns_fixed_not_replaced - the Ns fixed last timestep was not replaced this timestep (Q_rel is declining)
Ns_loss_not_replaced - the Ns lost last timestep was not replaced this timestep (Q_rel is declining)
