Ludovic Courtès 1a706ff5cf base32: Use a custom error condition instead of 'misc-error'.
Suggested by Christopher Allan Webber <cwebber@dustycloud.org>.

* guix/base32.scm (&invalid-base32-character): New error condition.
  (make-base32-string->bytevector): Use it instead of 'error'.
* tests/base32.scm ("&invalid-base32-character"): New test.
