I have a case where I have incoming data as unknown and I need to parse it as the input of the schema.

I can not parse it as output, because it might not pass all of the validations defined on the schema.

Internally, Zod's .safeParse should do these two steps:

• see if the given value adheres to the input schema
• parse the input schema to the output schema

Is there a reason why .safeParseInput does not exist and would you be open to a PR that would implement it?
