what to do if import doesn't exist in project dependencies?

[peakle]

currently ruleguard fails if it doesn't find package from dsl.import method

[mem]

This might be related to #253 and #408

@mem this issue about third party packages imported in rules such as this one for example: https://github.com/delivery-club/delivery-club-rules/blob/462a5e373a3d63ec51a8687cbb6dbc0379ac30b3/rules.go#L487

solutions that i can imagine now:

• add option (disabled by default) which will skip rule if imported package doesn't exist in project
• always skip rule if it doensn't exist in project

what do you think @quasilyte?

another one solution:

• filter func in Importer which can be called (if exist) after/before Import method
