Switched the stream << for c-strings to take a templated array param (since we never stream user-built c-strings, only string literals). For this, refactored the escape character display

Added constructor to the Emitter with a stream, so you can write directly to a stream instead of our temp

Fixed when we emit the doc start (only if there already is a document in the stream, and we're about to emit a new node)

Renamed the base64 methods, and switched the EncodeBase64 one to return a string (to make it easy to use elsewhere)

Refactored the base64 binary to its own space with a unified class that (will) be used for parsing (in addition to emitting)
