[daip] AIPS Data Importing

I have taken another look at the issue of writing a translator program
to swap byte order.  There are lots of file types:

MA, UV are all floats
RL all character
HI, MS, CA  simple structures w character and no double precision

CB - complex header structure but I already have a translator to/from
     network order  for XAS's image catalog

The Tricky ones will be PL (plot), SL (slice), TG (TGET), SG
(SAVE/GET) but I bet that a dumb routine that swaps any word that is
not all legal characters should work since none of these has any
double precision data.

Then there are tables - quite complex but a self-defining structure
that is amenable to analysis independent of the 24 types I counted.

It will take a while to write, particulary the table part and to
debug.  If you have some time, however, I think I am going to do this.
(You are not the first nor the last to encounter this problem.)
