Feat/base64

[ponderingdemocritus]

• Implements potential structure of a base64 JSON

1. We store pre-encoded values in a lookup table
2. build assembles the encoded values into an array
3. A client can decode then concatenate the strings to build a metadata standard json to be used across marketplaces

Benefits of this:

• Dynamic on-chain metadata as the Realm/Adventurer evolves over time

NOTE- This is branched off the pending combat PR. Ignore those files. Only look at the new Base64 dir

Was thinking - why base64 encode at all? It's JSON, not a binary format, so I think just data:aplication/json, ought to work.

[ponderingdemocritus]

this is a fair point. That makes it cleaner

closing as we won't use base64 for these
