Adding Vec<u8> conversion

[haixuanTao]

Some people might not know how to go from ArrayData to ArrowData using the make_array and to_data method.

This conversion makes it simpler.

It also add a way to quickly get a Vec<u8>.

Example:

                    let a: Vec<u8> = vec![1];
                    let b = ArrowData::from(a.into_arrow().into_data());
                    let c: &[u8] = (&b).try_into()?;
