Avoid buffer overflow in ada_decode
A bug report pointed out a buffer overflow in ada_decode, which Keith
helpfully analyzed. ada_decode had a logic error when the input was
all digits. While this isn't valid -- and would probably only appear
in fuzzer tests -- it still should be handled properly.
This patch adds a missing bounds check. Tested with the self-tests in
an asan build.
