This might not work, since FuzzCrossG2Mul is a prefix of FuzzCrossG2MultiExp
Go complains on my machine about it:

go test --fuzz FuzzCrossG1Mul
testing: will not fuzz, -fuzz matches more than one fuzz test: [FuzzCrossG1MultiExp FuzzCrossG1Mul]
FAIL
exit status 1

The way I found to fix it, was to specify FuzzCrossG1Mul. with a trailing dot.
I don't how if the compile_fuzzer script will work with this, but I think we should give it a try like it is right now and fix it up if necessary

I think FuzzCrossG1Mul$ is another to way to make it work. However, we can try it as is. The compilescript passes it to gofuzz-shim. Seems to me that it's parsed literally, not regexpy: https://github.com/holiman/gofuzz-shim/blob/main/main.go#L95
