> ArrowWriter StringWriter not using position of ByteBuffer holding data

>
> When ArrowWriter is copying a StringType column to ArrowData, then
> StringWriter gets data as a ByteBuffer and sets the ArrowBuf using a position
> of 0. This currently works because of a bug in Arrow ARROW-1443 that was not
> making use of the position. This has been fixed as of Arrow 0.7.0 and this
> surfaced when testing out this version. To fix this, the position of the
> ByteBuffer should be passed into {{setSafe}} instead of 0.
