feature: Add a flag to determine the targeted versions to cmd/compat

[ntnn]

Feature Description

As noted in a TODO it would be nice to be able to pass the targeted versions instead of just using the first one:

kcp/cmd/compat/main.go

Line 65 in 301a8f7

// TODO: take flags for desired versions, instead of just assuming the first.

Proposed Solution

Add flags indicating the targeted versions
