SCUBA2: FTS-2: Additional primitives in progress

These primitives are a work in progress.
- Some still have hard coded data paths to calibration files
  that should be moved and referenced in their proper place.
- They require completion and testing before being incorporated into
  the official Starlink smurf ORAC-DR release.
- They are not currently referenced by the intended REDUCE_FTS_SCAN recipe.
SCUBA2: FTS-2: Change orac_print to orac_say

Set band specific bounds
SCUBA2: moved FTS-2 band boundaries to HELLO.

This makes them available to all primitives from a single place.
