Create sub-function to identify RNA expressed transcript as opposed to full gene model

Create sub-function to identify RNA expressed transcript as opposed to full gene model. Without this, issues in visualization arise for certain genes that have a very large gene model, but a smaller transcript model that is actually expressed.

Counts data by transcript could be utilized, but would need to use ensembl id. Could write another sub function to check transcript id and convert, if necessary. But, may not be most pragmatic if user has bigwigs but no counts, or counts summarized by gene as opposed to transcript.

Other option is bigwig signal average summary per transcript within gene model, and decision making then. Foresee conflict if multiple transcripts of significantly varying size/length have close enough coverage.
