PartialSchemable
import type { PartialSchemable } from "https://github.gh-proxy.cn/raw.githubusercontent.com/baetheus/fun/main/schemable.ts";Takes a struct of Schemables and returns a Schemable for a struct that matches, key for key, the input schemables but the values can also be partial.
ie. { str: StringSchemable, num: NumberSchemable } becomes Schemable<{ str?: string, num?: number }>
