[Feature]: Augment Mgmt_Quant report with recruitment values

[Rick-Methot-NOAA]

Describe the solution you would like.

The Mgmt_Quant report lacks information on recruitment levels. This seems useful to add:
#_Mgmt_Quantity
SSB_unfished 52620.6 0
Totbio_unfished 131373 0
SmryBio_unfished 130864 0
Recr_unfished 7070.75 0
SSB_Btgt 17996.2 0
SPR_Btgt 0.511505 0
annF_Btgt 0.0768579 0
Dead_Catch_Btgt 2679.56 0
SSB_SPR 10092.8 0
annF_SPR 0.11536 0
Dead_Catch_SPR 2286.66 0
SSB_MSY 18794.8 0
SPR_MSY 0.522772 0
annF_MSY 0.0737495 0
Dead_Catch_MSY 2682.26 0
Ret_Catch_MSY 2682.26 0
B_MSY/SSB_unfished 0.357176 0

Heads up for r4ss. The _Mgmt_Quantity report already shows Recr_Unfished. I want to add Recr_SPR, Recr_Btgt, and Recr_MSY as part of the expanded output associated with understanding how spawner-recruitment interacts with time-varying biology.

No problem. The only place I see that makes a difference would be in the time series plot where it filters to get the standard deviation of the year-specific derived quantities and previously excluded "Recr_Unfished" specifically. I've just changed that in r4ss commit 1c22a4d, so it will exclude anything which doesn't have a numerical value after the "Recr_".

I agree that the additional quantities could be helpful and good to have in the table.
