Some warnings

[targos]

Just noting a few warnings I got while preparing the v9.9.0 release:

$ NODE_OPTIONS="--trace-warnings" changelog-maker --group --start-ref v9.8.0
(node:10896) [DEP0005] DeprecationWarning: The Buffer() and new Buffer() constructors are not recommended for use due to security and usability concerns. Please use the new Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() construction methods instead.

@targos could you please try #61?

I've confirmed this will be fixed when gitexec is updated with the newer bl version.
