update to build with utils v1.4.0

[Trek Hopton]

The light-netsender (PR #103) uses utils 1.4.0, but some netsenders won’t build using this newer version. We get the following error:

# bitbucket.org/ausocean/iot/pi/cmd/gpio-netsender
pi/cmd/gpio-netsender/main.go:53:7: undefined: logging.CSVLogger
# bitbucket.org/ausocean/iot/pi/cmd/log-netsender
pi/cmd/log-netsender/main.go:45:10: undefined: logging.CSVLogger

These should be updated to use the new logging version in utils.

Update to use utils v1.4.0 (also remove log-netsender)

• gpio-netsender: update to use latest utils
• log-netsender: remove this command, no longer needed
