Claiming namespace pixiedev

[pixiedevpraveen]

Hi,
I am Praveen Yadav, I do publish extension for vscode in vscode marketplace and just now want to publish my extensions on open vsx too. But in vscode marketplace my username is pixiedev and here, I can't change it, because open vsx took it from my github username. So kindly verify me as owner of pixiedev namespace.
