basenc: command not found; Unable to locate package basenc

In bitcoin.sh, consider changing
basenc --base32 |
to
base32 |

Ephemeral google cloud shell uses GNU bash, version 5.0.3(1)-release (x86_64-pc-linux-gnu) and coreutils 8.30-3.

prove t/*.t.s currently throws: bitcoin.sh: line 468: basenc: command not found

"basenc" utility not available in my reasonably modern instance:

$ sudo apt install basenc

From https://github.com/coreutils/coreutils/blob/00ea4bacf6063ccc125209d5186f8f2382c6f0d4/NEWS

* Noteworthy changes in release 8.31 (2019-03-10) [stable]
** New commands
  basenc is added to complement existing base64,base32 commands,
  and encodes and decodes printable text using various common encodings:
  base64,base64url,base32,base32hex,base16,base2,z85.

Workaround: after changing, in bitcoin.sh, basenc --base32 to base32 (and installing "dc"), all tests PASS:

$ time prove t/*.t.sh
...
All tests successful.
Files=10, Tests=398, 831 wallclock secs ( 2.18 usr  1.65 sys + 363.87 cusr 489.95 csys = 857.65 CPU)
Result: PASS

fwiw, I've submitted feedback to google cloud shell to install "dc", and upgrade "gnu coreutils" to 8.31+.
