use of bedGraphs in genomic_signal

[magruca]

In the original 2014 publication, it says that we can obtain aggregated read density over features of interested using bedGraphs. For strand-specific data (e.g. nascent) it would be nice to be able to use bedGraphs in the genomic_signal function as they're easier to concatenate pos/neg strands (as opposed to bigWigs where you're forced to separate based on strand due to the restriction on overlapping coordinates).

Is there a way to do this currently that I've missed? If not, I guess this would be a feature request.

Thanks!
