🐛 Fix MaxUint32 assignment to platform int

[bendoerr]

This fixes an issue where math.MaxUint32 is assigned to a platform
dependent int type. This works on 64-bit platforms without issue due to
there being plenty of space. On 32-bit platforms this is wrong and will
not compile as math.MaxUint32 > math.MaxInt32.

Would you like me to also open an associated issue?

Looks like the build failed due to a missing golangci-lint.

golangci-lint run
make: golangci-lint: Command not found
Makefile:27: recipe for target 'lint' failed
make: *** [lint] Error 127
The command "make lint" exited with 2.

Thanks. No need for a separate issue. I have ported the CI from Travis to GitHub Actions; if you rebase your work on master then the CI should pass.

Please also make the same change to expressions.y line 105. y.go is generated from this file.
