Add large block support to zpios(1) benchmark
As part of the large block support effort, it makes sense to add
support for large blocks to **zpios(1)**. The specifying of a zfs
block size for zpios is optional and will default to 128K if the
block size is not specified.
`zpios ... -S size | --blocksize size ...`
This will use *size* ZFS blocks for each test, specified as a comma
delimited list with an optional unit suffix. The supported range is
powers of two from 128K through 16M. A range of block sizes can be
tested as follows: `-S 128K,256K,512K,1M`
Example run below
(non realistic results from a VM and output abbreviated for space)
```
--regioncount=750 --regionsize=8M --chunksize=1M --offset=4K
--threaddelay=0 --cleanup --human-readable --verbose --cleanup
--blocksize=128K,256K,512K,1M
