Field inline definitions should be able to set required

[Jaymon]

Turns out, I don't like this syntax:

class Foo(Orm):
    class bar(Field):
        type = int
        options = {"required": True}

And I should be able to do:

class Foo(Orm):
    class bar(Field):
        type = int
        required = True

Any named arguments in __init__ should be top level properties.

At some point between April 29 and June 25, 2021 this got addressed
