Marvin 5.1.0

[Martin]

I have just released Marvin 5.1.0. My estimate is that it is about 40-50 elo stronger than 5.0.0.

From the release notes on GitHub:
* New NNUE net, net-ca6610a.nnue
* Optimized NNUE inference code
* New razoring margins
* New futility margins
* Some SMP bug fixes
* Fixed a bug in the parsing of the setoption UCI command
* Fix calculation of hash usage

The razoring and futility margins were automatically tuned using the tool introduced here, forum3/viewtopic.php?t=71650. Thanks to thomasahle for providing this great tool!

Thanks to everyone testing and showing interest in my engine!

FRC support is on the todo list, but I'm not sure when I will get to it.
