[Bug]: Ctl file Age for L1 and L2 issue with growth option 8

[e-perl-NOAA]

Describe the bug

From Mark Maunder:

In the control file we have
“999 #_Age(post-settlement) for L2 (aka Amax); 999 to treat as Linf”

Interesting, in the control new we get
“0 #_Age(post-settlement) for L2 (aka Amax); 999 to treat as Linf”

In the ss3-source-code, we have the following:

if (Grow_type == 8 && AFIX2 != 999)
   {
     warnstream << "AFIX2 set to 999 for grow_type==8 because only Linfinity allowed for growth cessation ";
     write_message (ADJUST, 0);
     AFIX2 = 999.;
   }
   if (Grow_type == 8 && AFIX != 0.0)
   {
     warnstream << "AFIX set to 0.0 for grow_type==8;  growth cessation ";
     write_message (ADJUST, 0);
     AFIX2 = 0.0;
   }

Suggested changes:

1. The second warning should be changed to AFIX = 0.0;
2. Also suggest changing AFIX to something more intuitive, such as what it is called in the control file Age(post-settlement) for L1 (aka Amin)

To Reproduce

1. Create a model that uses growth cessation (option 8)
2. Set Amin as 1

Expected behavior

Get a warning to set Amin as 0

@Rick-Methot-NOAA I don't mind making this small change since it's straightforward but if you would rather do it as a part of what you are working on like you mentioned in your email, I'm fine with that too.
