fetch(attrs, field)

@spec fetch(map(), atom()) :: {:ok, term()} | :error

Fetches field from attrs under its atom key, then its string key.

Returns {:ok, value} when either key is present and :error otherwise.

take(attrs, fields, clearable_fields)

An absent field is omitted. An explicit nil is kept only when the field is listed in clearable_fields; otherwise the nil submission is dropped.
