Implement precision set_position for RT-21 

The RT-21 will accept the command 'AP1XXX.Y<CR>;' which allows settings
to 1/10 of a degree.  XXX must be zero padded.  '<CR>' causes the RT-21
to rotate to the position immediately with out the need for a following
'AM1;' command.

Tested by Will, WC2L.
