fix: avoid errors during logging of requests/responses (#188)

Fixes #179

This commit slightly modifies how requests and responses
are logged when debug logging is enabled to avoid
any JSON marshalling type errors.
We no longer use JSON.stringify() to format
the request and response objects, as they
actually aren't needed because the
logger.debug() and logger.error() functions
can handle objects just fine and do a decent job
of pretty-printing them.
