base64 to json

multipart project 2
part 1 of, I don't know, like 5

Background:
Importing Base64Decoder adds a lot to the SWF size. Convert
a base 64 encoded string to an array (note that this
increases the AS size). Determine if this results in a
smaller SWF file.

Task:
- learn how to use minimalcomps
- decode a base 64 encoded string
- write a JSON array of values
- check how this affects SWF size
