If you'd like to implement a workaround, that's totally fine. I haven't had
much time to code over the last week but hoping to get this done this week. I
can open a new PR (probably will need a new JIRA for the custom_metadata
plumbing) if you leave your branch around for me to use as a starting point

> Some libraries represent boolean data as a single byte per value as a vector
> of int8/uint8 1's and 0's. It would be useful to be able to retain this
> metadata as an optional field on the {{Bool}} table in {{Schema.fbs}}
