[enhancement] support calling other scenarios in the same (implied) feature by tag

idea via https://stackoverflow.com/q/66328766/143475

I think it is a good idea to support * call read('@sometag') and look within the same file.

it can make self-contained examples easier, and we can optimize to not re-parse the feature etc.

on second thoughts - no. the reason is we want to encourage re-usable routines to live in separate features always, typically with an @ignore tag or tucked away under classpath: etc

the moment you tag a Scenario in the same feature file, it will run by default unless you a) add an @ignore tag and b) make sure you run so that @ignore is excluded which gets really confusing
