x509.name.build without sorting

[baynes]

It would be useful for asn1crypto.x509.Name.build()` to have an option to turn off the sorting the relative names into its preferred order and keep the input order. Some specifications require their own specific order.

You don't have to use build if you don't want that behavior.

If you've got an idea of an enhancement, also feel free to propose via a PR.

@wbond thanks for this nice library. Brilliant work!

@baynes do you know which specifications require a specific order?

I still think that this feature is useful to work around some legacy/buggy libraries or external API.

I found this issue with the IBM Data Power Gateway.

I went with a simple patch. If name_dict is already an OrderedDict, don't sort it.

I am not sure if this is the best general solution.

I am not a fan of flag arguments, but maybe Name.build(name_dict, sort=False) can also do the job.

Cheers
