Create schema without default values

[macmillen]

When creating schemas I don't always want to set initial values.

Let's say we want to describe this type in a schema:

type ComponentMap = Record<string, { id: string; name: string; }>;

How the current schema builder works is that you have to pass in default values like so:

s.obj({
  key: s.obj({
    id: s.con(""),
    name: s.con("")>
  })
})

There are a couple of problems with this:

1. we have a default value { key: { id: "", name: "" } } that we have to override
2. we have a key key but in this case I just want to have a Record<string, ...>

Ideas:

• make default values optional or provide an option noDefaultValues
• provide a s.record() schema type like zod does

Examples:

s.record(
  s.con<string>(), 
  s.obj({ 
    id: s.con<string>(), 
    name: s.con<string>() 
  })
)

I found out that there is a .map builder which solves issue 2. but issue 1. still remains
