🐛 RNA Seq files should not require a matched tumor-normal pair to begin embargo #141
Description
Describe the bug
The embargo start rules for a file require their donor to have a matched tumor/normal specimen pair. However, this should only apply to DNA files.
RNA files (RNA Seq for example) can skip this check and begin the embargo process without the matched file. Core clinical and song published rules still apply.
Steps To Reproduce
Donor with only one genomic file in song, adn that file is RNA-seq file for a tumor specimen.
Donor is core complete.
This file won't begin embargo process.
Expected behaviour
This donor should begin embargo stage and be indexed.
Suggested Fix
This matched tumor/normal pair rule is applied here: https://github.com/icgc-argo/files-service/blob/develop/src/services/embargo.ts#L185
A check needs to be added to not require this if the specimen in question is RNA data.
