MDT-4000-R4 - 6/1/2024

This release includes the following elements:

MDT-4000 fw v1.3
- Update the DHCP code so it forms the request with the same fields
  as used by Windows 11 to help with compatability with various
  DHCP servers.
- Update the LAN code to handle time deltas for DHCP more accuratly
  so the system will not request a IP renewal until there are about
  30 seconds left on the current lease.
- When switching from DHCP->STATIC->DHCP, make the system send another
  DHCP request sooner, about 10 seconds after the MAC reports it is linked.
- Add "GOTO SHORT <target deg>" command that makes the turntable goto the target
  position using the shortest path.
- Add "GOTO HOME" command to make the system "unwind" back to the 
  current zero reference position.

MDT-4000 CLI (mdt4000util.exe) v2.0
- The new commands below require the turntable to have fw v1.3 or later.
- Add the "--goto-shortest <deg>" command.
- Add the "--goto-home" command.
- Update the "--goto-position" command so it handles 0.0 asa positive value that
  results in CCW rotation.
- Rename the "--goto-position" to be "--goto-positive" which uses CCW rotation.
- Add the "--goto-negative" command which uses CW rotation.
  These two commands are needed in order to allow the user to specify how
  to move to "0.0".  The previous --goto-position used the polarity of the
  target position to detetermine rotation direction and 0.0 is a positive number.
  This prevents the user from specifying which rotation direction to use when
  moving to "0.0".
- Remove the --list command because it was not implemented and returned no data.
  We can add this command in the future if/when we add the other commands required
  to fully configure the turntable with all of the parameters that can be set via
  the local touchscreen.
