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. closes https://github.com/official-stockfish/Stockfish/pull/3456 No functional change
