You sure you want an *editor*, as in "you plan on edit things"?

If not, hexdump -C is your friend (it will abbreviate reams of
zeros and other repeated stuff by default). From hexdump's fine
manual:

  The options are as follows:
  [...]
  -v  Cause hexdump to display all input data.  Without
      the -v option, any number of groups of output lines,
      which would be identical to the immediately preceding
      group of output lines (except for the input offsets),
      are replaced with a line comprised of a single asterisk.
