faster dbo.ufn_vbintohexstr - varbinary to hex

Here's an alternative to Clinton Herring's ufn_vbintohexstr which should be much faster with large varbinary values.

By adding 6 to a hex-digit in (@vbin&15), you have a value from 16 […]

Challenged by Hans Lindgren's stored procedures of the same name, I created this. Note that it produces strange results on non-hexadecimal strings, overflows at 0x80000000, and could have issues with byte-ordering on some architectures.How does it work?
