Allow frequency weights

[mkaulisch]

I often work with data that is collapsed. It would be cool if frequency weights and/or importance weights would be allowed. The latter because sometimes I use frequencies with decimal numbers.

that should be easy to add. if you can share a basic example of data with and without weights, i can implement it fairly fast.

Have a look at this code example - from Discord channel

This code also generates an error code

PS: @asjadnaqvi has explained that the data in the form shown in this post: https://github.com/asjadnaqvi/stata-alluvial/issues/3#issuecomment-1382356172 - is not correct - and the error is correct.

Weights added in v1.1 but need further testing.
