PHREEQC: Bug fix of incorrect mass added in solid solutions with a component
containing an element not present initially, but added with
INCREMENTAL_REACTIONS.
PHREEQC: Enabled active_fraction factors for EXCHANGE_SPECIES in Pitzer activity
models, and generally improved the convergence of exchange calculations with
active_fraction factors.
Active_fraction factors are useful for modeling non-ideal ion exchange, see
https://hydrochemistry.eu/exmpls/a_f.html for an example of active
fraction model for varying exchange selectivity.
The aquia example https://hydrochemistry.eu/exmpls/aquia.html </A></I> now runs 3
times faster.

for a diffusion calculation. Now gives an error message.
