Accept subset of the Enum values

[ADR-007]

Hi there,

I propose to change this
kwargs['choices'] = tuple((e.value, getattr(e, 'label', e.name)) for e in self.enum)
to this
kwargs['choices'] = tuple((e.value, getattr(e, 'label', e.name)) for e in kwargs.get('choices', self.enum))
to have posibility accept only part of the enum.

This is a good idea, but we must then make sure the user's choices are in fact valid values for the enum.

Hello,

Yes It could be really useful to subset Enum values by adding a parameter on the field for exemple in serializer. Something like that:

class GatewayName(Enum):
    PAYPAL = 'Paypal'
    STRIPE = 'Stripe'
    WESTERN_UNION = 'Western Union'
    WALLET = "Wallet"
    OTHER = "Other"

    class Labels:
        PAYPAL = _('Paypal')
        STRIPE = _('Stripe')
        WESTERN_UNION = _('Western Union')
        WALLET = _('Wallet')
        OTHER = _("Other")

class DepositSerializer(EnumSupportSerializerMixin, serializers.ModelSerializer):
    gateway = EnumField(GatewayName, required=True, choices=(GatewayName.PAYPAL, GatewayName.STRIPE))

But now choices are not taking in account and the serializer accept all enum values.
