Transcoder updates for bitrate validator warnings (#106)

* Transcoder updates for validator warnings (gop, max-bitrates) for #50

* Make the variant settings easier to set/read in code

* Update test to reflect update to transcoder

* Reduce the buffer to give it a little more room to improve the quality. It feels a bit crunched right now.

* Fix test due to changed bitrate buffer ratios

* Tweak buffer size one more time to get errors in the validator to zero

* Saw errors w/ different bitrates, so tweaking it again
