Exclude VCR cassettes from Danger bot
Problem
When Danger bot does it's evaluation of changes in an MR, VCR cassette changes are factored into the warning about if a MR is too large. This can totally skew the perception of the MR being too large and can make the warning useless for any MR that includes VCR changes.
Proposal
We should update Danger bot to exclude VCR cassettes from this warning. VCR cassette changes aren't generally a concern as we can/should re-record cassettes commonly. These can largely be ignored by the reviewer.
Result
Improved stats regarding MR size.
