Swap from Cutechess to fast-chess

[AndyGrant]

Steps:

• Configuration settings in Config/config.json to point to a fast-chess repo and ref.
• Enforce a gcc or clang requirement once again for workers, to build fast-chess
• Remove cutechess binaries from the repository
• Upon update, delete any local copies of ob-fastchess and ob-fastchess.exe
• Add fastchessVersionRef endpoint to get the repo/ref for fast-chess when missing. Build.
• Include the fastchess --version output in the worker info, and display it on the machines page
• Determine all changes needed to the Cutechess Command builder
• Determine any changes needed for parsing fast-chess output, specifically for crashes / stalls / etc.
• Determine behavior when killing fastchess mid-workload on both Windows and Linux, concerning PGNs.
• Disable, or ensure support for bogus options of -tb for syzygy adjudication, until supported.
• Manually disable affinity code for now via the command, if one is allowed.

After:

• Remove the use of the py-cpuinfo library, as it concerns CPU flags.
• Instead depend on gcc/clang's march=native defines ( $(CC) -march=native -E -dM - )
• Use this for setting CPU flags, and for the determination of binaries for private engines.
• Collect information about this output for ARM and Mac systems to be sure its workable..
• Distinguish between x86 and ARM platforms, and convey this in the client info.
• Split the requirements for engines into the individual platforms.
• Support ARM for private artifacts, without breaking existing use cases.

Attaching the two text files here too, just in case.
