Environment

Alpine Linux 3.24.1 on 32-bit archs (armhf, armv7, x86)

Describe the bug / provide steps to reproduce it

Since b6b4ae4 you parse COMPOUNDMIN and COMPOUNDRULEwith strconv.Atoi, which is ParseInt(s, 10, 0) where bit size 0 is the native int. This means the boundary for absurd/unreadable values depends on the target word size. Meanwhile TestCompoundMinIsBounded encodes the 64-bit behaviour, causing the following failure on 32-bit targets:

--- FAIL: TestCompoundMinIsBounded (0.00s)
    aff_test.go:382: "COMPOUNDMIN 9223372036854775807": COMPOUNDMIN stanza had "9223372036854775807" expected number

I think these values should both be parsed as int64 with ParseInt(parts[1], 10, 64) to avoid making incorrect assumptions about word size?
