Joost VandeVondele 48df0754bc Add command line flags to link to information 
This patch provides command line flags `--help` and `--license` as well as the corresponding `help` and `license` commands.

```
$ ./stockfish --help
Stockfish 200522 by the Stockfish developers (see AUTHORS file)

Stockfish is a powerful chess engine and free software licensed under the GNU GPLv3.
Stockfish is normally used with a separate graphical user interface (GUI).
Stockfish implements the universal chess interface (UCI) to exchange information.
For further information see https://github.com/official-stockfish/Stockfish#readme
or the corresponding README.md and Copying.txt files distributed with this program.

```

The idea is to provide a minimal help that links to the README.md file,
not replicating information that is already available elsewhere.

We use this opportunity to explicitly report the license as well.

Joost VandeVondele dc4983327d Update WDL model for NNUE 
This updates the WDL model based on the LTC statistics in June this year (10M games),
so from pre-NNUE to NNUE based results.

(for old results see, https://github.com/official-stockfish/Stockfish/pull/2778)

As before the fit by the model to the data is quite good.

Tomasz SobczykandStéphane Nicolet 2e745956c0 Change trace with NNUE eval support 
This patch adds some more output to the `eval` command. It adds a board display
with estimated piece values (method is remove-piece, evaluate, put-piece), and
splits the NNUE evaluation with (psqt,layers) for each bucket for the NNUE net.

Example:

```

./stockfish
position fen 3Qb1k1/1r2ppb1/pN1n2q1/Pp1Pp1Pr/4P2p/4BP2/4B1R1/1R5K b - - 11 40
eval

Tomasz SobczykandJoost VandeVondele 58054fd0fa Exporting the currently loaded network file 
This PR adds an ability to export any currently loaded network.
The export_net command now takes an optional filename parameter.
If the loaded net is not the embedded net the filename parameter is required.

Two changes were required to support this:

* the "architecture" string, which is really just a some kind of description in the net, is now saved into netDescription on load and correctly saved on export.
* the AffineTransform scrambles weights for some architectures and sparsifies them, such that retrieving the index is hard. This is solved by having a temporary scrambled<->unscrambled index lookup table when loading the network, and the actual index is saved for each individual weight that makes it to canSaturate16. This increases the size of the canSaturate16 entries by 6 bytes.
