Mangled PRs

[dryajov]

I had a few issues with PRs being mangled (by github?) in this repo. I've reported the issues with github support, but meanwhile #4 seems to be holding up correctly.

What happened:

• I've rebased some commits in the original PR ( Feat/pull mplex #1) to make it commitlint compliant
• after pushing to the PR, github auto-closed the PR (claiming it was me), and didn't allow me to reopen it
• creating a new branch and trying to create a new PR didn't work - github would present me with the old (closed) PR link and wouldn't allow me to create a new PR

How I fixed it:

• I had to reclone the repo and manually delete the local and remote branches
• after that I had to rebase the new branch with master, which allowed me to create a new PR
• however, subsequent attempts to fix commit messages let to the same behavior, which required creating a new branch and PR every time.

I've contacted github support, and left a description of the problem. This has left 3 (#1, #2, #3) mangled PRs behind. Please disregard those. Sorry for the spam everybody.
