Migration should allow choice of target #49
Description
Currently, the migrate command has an opinionated default. For example, if you migrate from chalk, we will always migrate to picocolors.
Depending on es-tooling/module-replacements-codemods#103, we may end up having multiple options (e.g. chalk to ansis).
In --interactive mode, we should let the user choose what to migrate to.
In non-interactive mode, we should default to a hard coded choice.
