feat: branding, implement standard-schema

[ssalbdivad]

This PR adds branding via the following chained API:

const t = type("string").brand("foo")

And the following native syntax:

const t = type("number#cool")

It also allows transforming between branded and associated versions of a given type, which determines whether attributes that don't exist in TS are preserved when inferring output:

const unbranded = type({
    age: "number.integer >= 0"
})

const branded = unbranded.brandAttributes()

const reunbranded = branded.unbrandAttributes()

It also adds support for Standard Schema v1.
