Race condition when setting log level

[jkessler93]

When setting the log level, Go detects a race condition between lines capnslog/logmap.go:212 and capnslog/pkg_logger.go:158. I think there should be a read lock before checking the log level in the functions in pkg_logger.

@jkessler93 if your application is a consumer of those modules, please beware of #57 (comment).

@lucab thanks for letting me know! Any idea when it might be removed?

[lucab]

@jkessler93 I don't think it is going to be removed anytime soon due to the number of still-existing consumers. But if you are starting a new project or actively developing something, please consider not using this module as it won't receive much development/maintenance.
