add aschmahmann to multicodec codeowners

[aschmahmann]

Summary

Add myself to the multicodec repo

Why do you need this?

I used to have permissions here, but they were dropped (not sure why nobody tagged me) and I'm still involved and look at PRs as time allows. Some PRs like multiformats/multicodec#375 were not reviewed by anyone else with access.

This shouldn't net change my permissions but using the "override" didn't feel appropriate so flagging by adding myself to codeowners.

What else do we need to know?

DRI: myself
