525bbab165 tests(crypto): update wycheproof testcase source and parsing 
The JSON schema of the test cases has slightly changed.
The "curve" field has moved to the "testGroups" level and the X25519 algorithm has been renamed,
which requires adjustments in the parsing code.

A duplicate definition of "ecdh_vectors" has also been removed.

1174648777 refactor(crypto): extract Cardano derivations to separate file 
Changes the API: all Cardano derivations will now produce a 96-byte
secret in the format of private_key + private_key_ext + chain_code.
This can then be trivially converted to a HDNode.

f051225730 feat(core,legacy): add support for Ethereum 64-bit chain_id 
* Changes from original PR

* Now that we are rejecting chain_ids of 0, we need to have the tests set the chain_ids to at least 1.

* Ran 'make gen' and uploaded changed files.

* Ran make style_check and fixed reported errors

* Added changelog files

* Reverted changes concerning chain_id 0 being rejected.

* Adds tests for MAX_CHAIN_ID and MAX_CHAIN_ID+1.  Also reverts MAX_CHAIN_ID to the previous value.

* Added missing whitespace around arithmetic operator.
