Support for Lake Shore Temperature Controller

• Extended NIRIs tcon record to handle a dual
  controller (the Lake Shore 340)
• Added device support for the Lake Shore
  (devTconLS340 and devAILS340)
• Added driver support for the Lake Shore
  (drvLS340)
• No changes required to use with Omega controller
