Import binary files as base64 encoded strings

[L0r3m1p5um]

I'd like to have a way to import binary files in to Nickel as Base64 encoded strings. This is the behavior I would want:

$ printf "\xFF\xFF" > binfile
$ echo "import \"binfile\" as 'Base64Encoded" | nickel eval
"//8="

The main use case I have for this is to create Kubernetes Secrets and ConfigMaps. Both those resource types support including binary data as base 64 encoded strings (Secrets base64 encode data by default, ConfigMaps support it through a separate binaryData field). Right now I need a separate processing step outside of nickel in order to generate configmaps like this since there's no way to import binary data into Nickel.

Do you have any idea how to handle the different variants of base64 encoding?

I don't know a better way than to just enumerate all of them, the way we did with base64_encode in the standard library. So I guess it could be 'Base64Standard, Base64UrlSafe, Base64NoPad, Base64UrlSafeNoPad.
