Fixed varint handling on btc tx parser and rsk trie parser (#128)

- Handling partial varint parsing in BTC tx parsing
- Fixing an issue when accumulating a varint raw data both in BTC tx parsing and RSK trie parsing
- Added both BTC tx and trie unit test cases
- Added an authorized signing test case to the signer tests
- Incidentally fixing a log message format
