Updated check_tfrecords usage in README.md

[jmarrietar]

Seems that in README.md the usage for check_tfrecords hasn't been updated yet.

Thanks for this @jmarrietar!

@cfezequiel do we want to add check into init.py or update line 74 below to include tfrecorder.check.check_tfrecords()?

Thanks for catching this @jmarrietar. We appreciate your contribution. I do think it may be better to add the check import to __init__.py for consistency with the other operations (e.g. client, accessor) so that import tfrecord would be sufficient to access them, as @mbernico suggested. But from tfrecorder import check would still be valid.

One Question @mbernico, Should I have open an issue first for this?. How would be the best way to report problems with the Tool, as I see is in early development. Also to ask questions about it.

Thanks!.

@jmarrietar Issues would be awesome for both problems and feature requests, but your pull request is much appreciated as well. We will take all the help we can get and would love to see a community built around TFRecorder. I posed some questions to @cfezequiel re style, but your PR is super valid and we appreciate it.
