ajv peerDependency

[gigaga]

Hi,

Thanks a lot for your work ;)
I found an incoherence between your github repo and what is published into npm registry. Indeed, in npm registry, ajv 6.x is declared as peerDependency but not in your code :(
https://www.npmjs.com/package/ajv-oai?activeTab=explore
I would like prefer using your code without this peerDependency declaration :D

Regards,
