Semantic version number branches not supported

My newer project used semantic version branches and this awesome tool only expects M.x-N.n branches.  My branch is 1.0.x

```
commerce_donation_flow on branch 1.0.x [+?] via 🐘 v7.3.22
➜ drupalorg issue:branch 3178042
The issue version branch 1.0.0-x is not available.
