matejcik	ff4ec2185e	core: refactor keychain to only support one curve at a time also make a cleaner distinction between keychain, seed, path This enables using `unsafe_prompts`, because with the original code, if there was no namespace match, we wouldn't know which curve to use. For ease of implementation, we use a LRU cache for derived keys, instead of the original design "one cache entry per namespace". SLIP21 is now treated completely separately, via `slip21_namespaces` and `derive_slip21` method. If more slip21-like things come in the future, we can instead hang them on the keychain: put a per-curve Keychain object accessible by `keychain[curve_name].derive()`, and the majority usecase will just pass around `keychain[curve_name]` instead of having to specify the curve in every `derive()` call. Or alternately we'll just specify the curve in every `derive()` call, whichever seems more appropriate.	4 years ago
