common/defs: add 'confidential_assets' section to coin definitions (#399) Enable 'confidential_assets' for Elements (following #66 and #317) to allow deriving confidential addresses and signing confidential transactions. The following Python helper script was used to update the JSON files: ``` import json import sys for f in sys.argv[1:]: d = json.load(open(f)) d["confidential_assets"] = None with open(f, "w") as o: json.dump(d, o, indent=2) o.write("\n") ``` Set it to `{'address_prefix': 4, 'blech32_prefix': 'el'}` for Elements. `coins.json` and `coininfo.py` were re-generated using: ``` $ pipenv run make gen gen_check ``` 2019-08-12 10:52:20 +00:00			`"confidential_assets": null`
