Since Himalaya is intended to be ran as a CLI in the terminal emulator
environment, their user experience could vastly improve with better and
more colorful error messages and logging.
This change will replace more minimal libraries for error-reporting/han-
dling with their more advanced counterparts.
Since these crates have tight integrations, this commit will change both
in one shot.
Also we have don't need env_logger any more. So I also have removed that
guy as well.
