> Issue Type: New Feature

> Reporter: Wes McKinney
> Priority: Major
>
> Presently, the TypedColumnWriter for booleans expects a {{bool*}} (i.e. 1
> byte per value). Some writers may also use a LSB-ordered bitmap, and we could
> write that directly rather than having to copy the bits into a temporary
> {{bool*}}
