Buffer overflow exception when input contains 'z's

[zaxdo]

When decoding, the formula for the output size is "input_size * 4 / 5", which does account for the fact that when input contains only 'z's output can be 4 times as large as the output.

@zaxdo not sure i understand.

I tried this:

    @Test
    public void testOnlyZInput() {
        String payload = "zzzz";
        String encoded = Ascii85.encode(payload.getBytes());
        assertThat(payload, is(new String(Ascii85.decode(encoded), StandardCharsets.US_ASCII)));
    }

[zaxdo]

Do Ascii85.decode("zzzzzzzzzzzzzzzzzzzzzz");

Fixed this using #10 with the help of @odisseus
Closing this issue.
