Member Request (#28)

I am Quentin Mc Gaw, a software engineer working the Go Polkadot host **Gossamer**.
I have been working full time on Gossamer since October 2021, mostly on the state trie and storage.
I have also made a [few minor pull requests](https://github.com/w3f/polkadot-spec/pulls?q=is%3Apr+is%3Aclosed+author%3Aqdm12) to the Polkadot specification repository.

I am requesting to join the Fellowship at rank 1.
