- use MetricVec family instead of Metric
- dynamic label values instead of ConstLabels
- use dto.Metric to gain histrogram value in exporter_test
- remove hash calculations

The escaping changed in 728bdc52ae, before
0.1.0. Add a test for the escape function, and test various cases,
including those mentioned in the README.
This reveals that the README is inaccurate, adjust it to what has been
the reality for many years. Fixes#97.
* Remove option flag
* Update NewExporter call signature to not take suffix boolean
* Update tests to reflect new behavior and signature
* Update documentation to reflect option flag removal
* add TCP StatsD listener support
* add listen-tcp flag to control UDP/TCP mode on same port
* statsdListenUDP/statsdListenTCP as string, and alias listen-address to listen-udp
* add stats for tcp error/line_too_long
* add test for TCP listener
Instead now we will send a warning message to the logs
and continue on with our day.
Also a guard has been added when we detect a channel has been
closed and the `Exporter.Listen` function will return out of
its loop vs always running. When a channel is closed there will
be no more data to consume, so this seems correct. It also allows
for a test to be written for the panic.
