findOrCreate should accept 'fields' to save

[sonirico]

Issue Description

Is your feature request related to a problem? Please describe.

CreateOptions has a optional property named 'fields' which describes which fields are writable, in order to prevent additional and/or malicious fields sent on payloads persisted in databases. However, FindOrCreateOptions does not provide such configuration to be set. Is that intentional?

Describe the solution you'd like

Some configuration flag to enable writes applicable to certain fields, as CreateOptions does.

findOrCreate does pass options to create method. I think typings can be improved. Please send a PR if you can spare some time
