dearblue 6c2f570d79 Fixed base64 decoding in mruby-pack 
Previously `\x80` was incorrectly mapped to `0`.

```ruby
"\x80\x80\x80\x80".unpack("m*")
# before => "\x00\x00\x00"
# after  => ""
```

The reason is that the C string terminator is placed in `base64_dec_tab[128]` and the array length is obtained by `sizeof`.
Therefore, the length of `base64_dec_tab[]` is strictly specified and replaced with element-by-element initialization.

Also, similar changes are made to `base64chars[]`.
